does the top loading coil have the std 3/8x24 threads for mounting?

I measure the top loading coil thread mount to be an 8mm x 1.0mm metric thread (standard fine metric thread). The RF connector is an SO-239. Mounting pole is 29mm ID, 32mm OD. It appears to be completely metric dimensions.

I want to run a splitter off this connected via 30’ lmr-400 to run ota dtv & sds-100. is this possible? what splitter?

Hi Aaron, It would be better to use a low-loss antenna switch such as the Daiwa CS-201. Switch the antenna to the scanner, or to the TV. If you want to use both at once, a splitter or multicoupler is needed. I suggest contacting the people at Scanner Master for their suggestions.

What is the best cable to use for uniden scanners? (sds100) will it overload the scanner?

LMR 400 cable. No it won’t overload the scanner .

How tall of a mast is recommended?

I used a Gable Antenna Mount and used two 5 ft sections for a total of 10 ft. 5 ft would have worked but 10ft worked better for my application. 5ft would be a good choice if using a Tri-pod Roof Mount. Just my opinion. Hope this helps.
