## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Excellent mount, Excellent performer
  

*by J***D on Reviewed in the United States on 24 June 2024*

This mount worked well on my 2020 F350 SuperDuty truck.  I  mounted it drivers side, near the rear of the hood and added some PPF under the mount to prevent paint damage.  I paired it with a Browning/Tram BR-180-B and have had a lot of good luck working all of the vhf/uhf repeaters around my area.

### ⭐⭐⭐⭐⭐ 







  
  
    Durable
  

*by J***M on Reviewed in the United States on 17 June 2024*

This thing is durable and made for heavier antennas. Works as it should!

### ⭐⭐⭐⭐⭐ 







  
  
    The best lip mount you could buy
  

*by M***. on Reviewed in the United States on 6 January 2021*

I used to have the older version of this mount years ago but left it on the car I sold. Then I bought a clone of this mount and used it for about 6 months until it was ruined by the elements. So I replaced that one with this one...the real thing. I didnt realize how much I missed it. This is the most solid lip mount I have ever seen. The bracket is solid when you tighten it. When I say solid, I mean it is so rigid that you will bend your lid before this thing would budge. The coax is very thin and it goes to an sma where it connects to an adapter to connect to the rig. This principle makes it super easy to run the coax because you are not trying to send a pl259 or n type through your paneling nor do you have to remove and replace the connector. I am not sure what type of coax it is and I don’t know how much loss it has but I’m also not using it for dx so It really doesn’t matter to me. This thing is really great and worth every penny.
