Do any members have experience between these two Comet antennas? Or compared with other antennas intended for fairly significant gain on GMRS frequencies?
As mentioned in a previous post, I have a Comet GP9 (base antenna) but the SWR is excessive since it is so far out of band and I don't think the Midland MXT400 rigs have power "fold back" for protection so we have been only running the mid power level at the most.
The GP9NCA may possibly be discontinued from what it looks like, but it has substantial gain for a consumer priced vertical base station antenna and several vendors indicate some inventory.
One other question. Has anyone rigged up an in-line tuner to flatten out the SWR on UHF antennas? I would expect that this would introduce losses, but the GP9 actually performs reasonably well at 25 feet height above ground and I could move it to 40 feet. I have never tried UHF tweaking , but, of course, there are many antenna tuners that we use routinely on the HF bands, but in that case it is more of tuning the antenna "system."
