The GP9 I used
Hello All,
I am looking to rebuild a 70cm repeater with an output within the ham band. We
currently have a non-tunable fiberglass comercial band antenna wich is giving
us a SWR of about 2:1. The first piece of advice we are looking for is
recomendations for replacing the antena. There are some
From the information you've provided I'm look hard at a Motorola R1225
or a pair of GM300s.
The diamond will certialy lower your SWR, but so will a 50 ohm dummy
load. Low SWR isn't the only concern any more than antenna gain is.
It's likely the Diamond will work, but these ham market antennas
Depending on what coverage you are looking to expect, will help you choose
the proper gain antenna.
A higher gain antenna is not always a good choice and can cause more
problems and poor coverage then you would expect nearby the repeater.
What is you HAAT? Are most the user going to be fixed

I changed sites and the repeaters each got their own
antennas. Then they performed roughly the same.
