This antenna's design & cord length is what makes it work
The RGTech Monarch Indoor Antenna performs better than any other FM antenna I have tried so far. My challenge is that I'm in a large metropolitan area but I'm trying to pick up a weak (100 watt) FM station across town (30-40 miles away). I prefer the FM version of the station to the AM version (as AM radio tuners don't sound as good as they used to - my Onkyo receiver is no exception, largely rolled off above 3 khz). Of course, this FM station comes in pretty clearly in my car but I struggle to get it in the house - even on the 2nd floor in my office. And with FM, the higher you place the antenna the better, as FM is largely 'line of sight' with the reach of its signal and your ability to receive it. I've had the RGTech Monarch Indoor Antenna in place, indoors on a wall near my ceiling, for about a week now. It works noticeably better than others I've tried from Terk and Bingfu (Terk amplified AM/FM tower, Bingfu FM dipole w/ 10' cord). These others have worked fairly well as FM antennas, though inconsistently - they need to be repositioned regularly for weaker stations or cannot support where they need to be placed (i.e. you think you've found "the spot" and then a few days later you have more static than signal - or "the spot" is an impractical location and you can't safely put the antenna there). But the RGTech Monarch has done significantly better with FM signals because 1) the antenna itself seems to be more sensitive 2) it is very lightweight for its size (which helps greatly with positioning it) and 3) it has a 15' cord that allows even more positioning flexibility. And for those who've not played around with positioning an FM antenna that much, there is a key factor to consider. The cord is also part of the antenna. Where you position the cord may make more of an impact than where you actually position the antenna itself, in many cases. While this antenna seems to be made to put it in a window or on a wall, you will have to move it - and the cord - around to see what works best. Be prepared to stick and unstick the antenna from different locations, several times. You might want to use some tape to place it on the location you want to try it at, before you actually use the built-in adhesive on the antenna. The built-in adhesive spots will become less sticky the more that you move it of course. This is also so that you can take your hand(s) off the antenna to see how it will perform. Any antenna tends to work better when you are touching it - so you need to step away from it to see if you found the right position that will work 'hands free' (unless you want to keep your hand on the antenna the whole time). :-) While it does indicate it's also an AM antenna on Amazon and on the product box, you'll also notice that it doesn't really mention AM frequencies on the other side of the box and the antenna only provides a single 75 ohm coax connection (with a few adapters). It seems like the mention of AM could be a misprint. On the other side of the box it talks about FM frequencies or DAB (Digital Audio Broadcasting, a European or non-US format - for this antenna 170-240 MHZ). So if your radio provides an AM connection this antenna can connect to, go for it - see if it helps. But I don't think this antenna is meant for the AM band. In my experience, most AM antennas require two wire leads (ground & positive) to connect to the receiver or tuner. For this price (I purchased it for about $20) I would give this antenna a try! I am very happy with it so far.

Easy to install, more stations, clear reception
I bought a table top AM/FM radio last week, and both with the internal antennae and the external FM antenna, I had good reception on a few stations, but quite a bit on static unless I tuned exactly on the frequency. Looked at various external antennae on Amazon, decided to try the RGTech Monarch Indoor AM/FM Antenna, although the ad wasn't crystal clear on setup. Package was delivered within 24 hours, and installation was simple: plug in the F connector at the end of the antenna wire, then determine where to stick up the antenna - up to 15 feet away. Instructions suggested putting it on a window - wouldn't work, nearest window has wooden struts on the pane and the 24-inch antenna wouldn't fit flat. So I stuck it on a large bookshelf that abuts the window, drew in the extra attenna wire and put it behind the bookshelf out so sight, turned on the radio, voila! More stations, clearer reception, no static on main stations I like. The antenna is thin and flat, and comes with double-sided tape on the back, easy to stick on pretty much any flat surface at least two feet long. No one will ever notice the antenna. (Illustration on the ad is confusing and unhelpful, but installing the antenna is easy as pie.

Does not work
I bought this antenna to replace a single wire antenna that shipped with my radio. I was hoping that this antenna would give better reception. It failed miserably. Not only did this antenna deliver a signal so much weaker than a simple piece of wire, but also picked up considerable static and noise. Even when placed against an outside window in many different orientations and positions it failed to perform.

I'm Impressed!!!
I'm Impressed! We live in a rural area of northern Michigan with no really large cities anywhere around us so the choice of radio stations is very limited for us. However there are a couple that come in good and there are several that come in somewhat. Sometimes with static, sometimes fading in and out. Our house is on a wooded piece of property surrounded by trees plus we also have a metal roof. That's an awful lot to ask of an inexpensive little indoor antenna to overcome. We first tried one of those Amplified Bow-Style antennas from another company. That was a total disappointment. It did not even work as well as the little single wire antenna that came with the stereo. We returned that Antenna to Amazon for a refund. We had also found this one at the same time we found the bow-style antenna so we thought we might as well give this one a try. Invented by a N.A.S.A scientist. Comes with a full money back guarantee. Why not give it a try? What did we have to lose? I'm impressed. This thing did wonders for our signal. While we did not pull in any additional station with this antenna it did clear up all the station we were already getting. Even the marginal ones. The static was gone and our other stations no longer faded in and out. It's super flat, Maybe the thickness of 2 pieces of heavy printer paper so it can be attached on a wall just about anywhere. It has a really long wire so you can move it around to find the best location to pull in your signals. It comes with a connector that looks like the one on your cable T.V. wire and it also comes with an adaptor. Unfortunately the adaptor did not fit our stereo. So, Back out to Amazon again for some research on adaptors. What I found out is that the adapter that it comes with is called a PAL Male adaptor. We needed a "PAL Female adapter." After looking around on Amazon some more we found just what we needed. Its called "PAL Female to Female F Coax adapter" I've included an image of the connector above. We now have a clean signal, a variety of channel to choose from and no more fading or static. The adaptor that we decided on was this one: Uxcell Antenna CATV TV FM PAL Female to F Female Jack RF Coax Adapter Here’s the link: https://www.amazon.com/gp/product/B00OK44Y6I/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 The adaptor worked great and this Antenna was just what we needed. We couldn’t be happier.

Cheap, broke easy.
Just a flat hard plastic with internal printed circuit, broke while sliding between window sash. Reception was not impressive, that is why i was trying to slide it to the exterior of the window when it broke.

FM Only
Worked well for my FM service. I live close to a small town and picked up stations from several adjacent areas. I used this for a late 80’s Nakamichi receiver I just dug out of the closet and it plugged straight in with the coax connection. Didn’t have to use the adapters. It looked a lot different from what the picture implied. There’s no aesthetics with this so it will need to be hidden away. It’s basically a black flat piece of plastic on the end of the coax. The 15’ cable made it easy to hide the cable to route to a good location. I moved it around in several locations and didn’t see any big differences. Ended up with it on top of a head high cabinet close to a window. I purchased this over several others because it was advertised as AM/FM. It has one coax connection that fitted the FM port but no mechanism for AM. My receiver has the coax connection for FM and two wire connections for AM. The instructions were silent on that. I’ll try the web site but as of now I’m not thinking there’s an easy way to use this for AM. Really misleading advertisement for looks and function. Seems to work well for FM if that’s what you’re looking for.

As advertised which is saying a lot for an antenna
I have tried a few different antennas for my receiver and at best have had limited or poor results. I realize my physical location in my house and other factors could be at play but none of the antennas I have tried to date obtained any better results than the basic ones that came with my receiver. This FM antenna has provided the best results to date and is an upgrade for sure. No miracles but much better and about what could be expected from a decent FM antenna - close to rivaling a decent car antenna’s reception when driving but not quite so good as that. Very much worth a try if you use over the air FM frequently and would like an upgrade.

BETTER THAN EXPECTED....
I have a very nice Sangean HDR-18 HD FM radio, which has a great tuner (and fantastic sound), but comes with a telescoping whip antenna. The whip provide only mediocre reception so I have been trying to find an indoor FM antenna that would improve reception, especially of some lower-powered classical stations in my area, and saw some flattering reviews of this one. I wasn't optimistic but for the price, I figured what the heck (plus you get a couple of connector convertors that, purchased separately in a store, would cost nearly as much as the antenna!). Well, I am impressed. After a bit of fiddling to find the sweet spot, I was able to get a solid, "full quieting," no hiss signal from a 250 watt (ERP) station 16 miles away. I also started hearing other stations that I was unable to receive clearly in the past. The thing to realize is that this antenna can be very directional. You may not be able to stick it in a window and get strong signals from every station you want; the window may not be facing in the right direction or at the best angle. I fortunately live in a wooden house and did not need to put the antenna in a window; it's behind a bookcase on a outer wall (where it's picking up the signals I want better than if it were in either of the two nearby windows, one facing west and the other north). So the message is: Don't just unbox the antenna and stick it to a window (with the built-in tape). First experiment with positioning, both in and near windows, especially if you are in a wooden building. Even if you are in an apartment framed in steel, where you must use a window, try as many different positions on the glass as possible before you actually tape it down. The antenna can function horizontally or vertically, but experiment to see what works best for the station(s) you want to pick up. Fortunately, the antenna comes with 15 feet of coaxial cable which allows a good deal of flexibility in positioning the antenna.
