WSEM262 Posted October 14 Report Share Posted October 14 Hmmm... now im thinking again. I currently have my 50w repeater connected via 35ft of LMR600 to a GP6NC on a 30ft mast at 1350ft asl and surrounded by hilly terrain.  I wonder if the GP9NC would be better or worse than the GP6NC in this area ???

I have both of these antennas. 30ft mast, 50ft LMR400. In my case, the GP9 worked better on VHF and the GP6 better on UHF. Don't know if it is the location of the antenna, the oak tree 20ft away or what but I had a better experience with the GP6 over the 9. I dropped my mast to 15ft and the GP6 made it just fine though the Cat3/4/5 hurricane that hit me last week in Tampa. Don't have to worry about the oak tree....it didn't. Power is still down, no air conditioning sucks. WSEM262 1 Quote Link to comment Share on other sites More sharing options...
BoxCar Posted October 14 Report Share Posted October 14 The GP9NC highest frequency is 450 MHz while the GP6NC's is 470 MHz. The 6 covers the GMRS frequencies while the GP9 cuts off below GMRS. WSEM262 1 Quote Link to comment Share on other sites More sharing options...

The straight GP-9 and GP-9N (ham version) is rated 144-148 and 440-450MHz. WSEM262 and WRYZ926 2 Quote Link to comment Share on other sites More sharing options...
WRYZ926 Posted October 15 Report Share Posted October 15 And even the standard dual band version of the GP9 can work just fine on GMRS. Each individual antenna can and will vary. My GP9 has a SWR of 1.5 across the 467MHz portion and SWR of 1.7 on the 462 MHz portion. I am at 15 or less for 2m and 70cm. Quote Link to comment Share on other sites More sharing options...
