We are a new ham radio club (RRARC) in TX with currently 60 members living in a 55 and over retirement community.? As you can imagine, we are tightly governed by HOA rules.??
?
We are about to install our repeater on the roof of the community clubhouse.? The clubhouse is on a hill with line of sight to the north and east approximately 8 miles.? To the west and south approximately 25 miles.
?
Being new, we do not have a repeater pair allocation yet.? Currently we are operating crossband, receiving on 144.650 and transmitting on 441.350.? These are test frequencies until we can get a permanent installation site and do some ERP mappings in order to request a frequency allocation.? Currently we are operating on a dual band antenna using a diplexer and a Yaesu DR-2x repeater.
?
Here is the question and our plan.? Since we will get one shot at antenna installation, we plan to install a Kenwood DB-408-B (450) antenna.? It is 8' 5" tall.? We plan to remove the top plug and install an ARX-2b Ringo on top.? It is 12' 5" tall.? We plan to receive on the Ringo and transmit on the DB-408.? This will be a temporary solution until we and do site surveys on both 440 and 2mtr in order to request our allocation.
?
Looking for opinions on how well this temporary crossband setup is going to work, using the top antenna for receive and the bottom for transmit with no diplexer since we'll have dual feed lines, and using the vertical stack to negate some desense.? We will be likely using 20 watts.
