B-Tech Nagoya NMO-200C 38.5" Antenna NMO Mount Dual Band VHF, UHF (155/460Mhz), Commercial Tuned Antenna (GMRS, MURS) (Requires NMO Mount)

Perfectly acceptable for my local use needs. From a pizza pan mount, pushing a 20w radio, I’m getting into a repeater 71 miles away from inside my home. VSWR is 1.7:1 from the frequencies I use

If you looking for a great antenna for your car, loook no further. Outstandingly good reception, especially for airband and will easily withstand legal road speeds without moving. Tested up to 120mph on private road with no issues. Connected to my TD-H3 handheld radio it performs brilliantly.

Easy to set up and SWR was insanely low at 147MHz (1.07 if I remember correctly). Tested the SWR while it was mounted on my car, so don't expect these results without a ground plane. Transmit and receive: Can now hit repeaters that I couldn't before with handheld antenna in the car.

I have 3 of these on different vehicles. Highly recommend them.

Used this to connect to a Quansheng handheld. I used it to reach a local repeater with the antenna sitting on a table on my porch and was able to hit a 2 m repeater about 6 miles away. I had tried a number of other whip antennas on the unit and the report back was the signal was strong however the mic volume was still low. It is the radio and not the antenna. Bonus I was able to pick up a linked repeater on 70 cm that was 50 miles away. This will end up on my car however it performed well even without a ground plane. The adapter is a bonus as eventually I will use this with a regular mobile unit. The price point is excellent and proves you can get in ham radio without breaking the bank.
