Got a antenna question that I'm not sure if its the antenna or if while switching antennas i might have damaged the mount.
My antenna is a roof top mount NMO connector. Drilled thru the roof of the car.
I had the following antenna on the car (Antenex Quarterwave - Unity Gain 19")
QW144 - Antenex Quarterwave Antenna (144-152MHz, Unity Gain, Stainless)
i upgraded from a 2m radio to a dual band radio.
Here is where my problem comes into play.
I installed the new dual band radio. Used the weather radio to test reception. After installing radio i turned in on and tuned into the weather radio freq (162.550) which is located 60 miles from where i was, using the above antenna (Antenex)
Recieved 7 of 9 bars on S meter.
Turned off radio and then went to upgrade the antenna to a Diamond NR72BNMO (Dual Band Antenna)
Diamond® Antenna ~ NR72BNMO Dualband Mobile Antenna
After installing the Diamond antenna turned the radio back on the the weather radio freq (162.550) now only had 1 of 9 bars on s meter.
Took Diamond back off and put Antenex back on and had 6 of 9 bars. Took off and put Diamond back on still 1 of 9 bars on s meter. The vehicles position didn't not change during antenna switching.
Looking at the antennas should there be that much difference?
The Diamond has gain as to where the antenex is just a unity gain.
Is it possible to have damaged the mount during the antenna switch?
Any suggestions on what to check?
