Looking for opinions on a gmrs base antenna setup.
Currently using a mobile nmo 5.5db whip on a mag mount, on top of my furnace chimney. Plenty of steel ground plane and it seems to work OK, but not great. 12' of RG58 with the mount and about 20' of RG8x to complete the feeder. This puts me around 3.5db loss in the coax. I can just barely pick up 2 different repeaters, each about 40miles away on a clear day with the monitor/squelch wide open.
Not the most ideal situation and i want to improve it.
First consideration is that i need 2 different antennas, a yagi (12-element PCTEL MYA45012) on a rotator and a 9db gain omni (Comet CA-712EFC), both on a switch. Seemingly, this would give me all the options I'm looking for. Long range sniper antenna with the yagi and good around-town simplex with the Comet. I will be improving the feeder lines significantly with lmr400, 600, or maybe even 1/2" hardline. All 'N' connectors and 'N' ported switch to keep loss at a minimum. Both would be mounted on separate masts (yet to be installed) on the roof, about 15' apart from each other.
My question is.... would a DB404 be equal to or superior in hitting the 40mile away repeaters? And if so, is the DB404 really all i need? From what i have read of Corey's DB404... sure seems like thats all i would need. However, I'm concerned with my urban location in the swamp of Indianapolis, lack of height on my roof, and trying to break a signal out of the trees as well as the lower lying swamp ground that is my neighborhood.
The price for the 2 antennas and feeders will end up costing about the same as just going with a DB404 out of the gate.
(no wifey-poo considerations and i could care less what the neighbors think)
