So, that DB-404 antenna sounds pretty amazing, Spaz, but it's a bit much $$$ for me to justify (yet).
Instead, I've ordered an Ed Fong DBC-1C kit (see https://bettersafera...ation-antenna/)
Reviews seem good, and it's the kind of kit project I'm happy to work on. Outsource the precise math to the PhD and do the PVC and cabling work myself...
Now, my question is this: Which of the following deployments is most likely to work for me?
Background: I'm trying to achieve simplex comms for emergency purposes with my wife at her office, roughly 3 miles away. Terrain is soft rolling hills in a suburban (northern Virginia) environment. She's already on the Alexandria repeater just fine, but I don't want to rely on that for emergencies.
Option 1 - Set up the antenna indoors near a bay window facing in the direction of her office.
Option 2 - Set up in my attic crawl space, semi-permanently mounted. (Town house with 3 floors. Attic is roughly 25 feet above ground.) The down side of this deployment is running the cabling.
Option 3 - Set up in the front or rear of the house, semi-obscured from view (so I don't get the wrath of the nanny state HOA). Again, cabling is an issue. I can put a hole in the wall, but I'd prefer to not add additional connections in the cabling. (Planning on a 20' stretch of high quality coax, with SO-239 connectors on either end.)
Side question - I've read in several places that the SO-239 connectors aren't optimum for modern UHF bands, but they seem to be the most common on antennas. Is it worth going with Type-N connectors at each end, or are the 239s adequate for normal use?
I should add I'm initially going to be working this with a BTECH GMRS-V1 handheld, hoping to get a 40-50 watt mobile at some point in the future.
First goal is simplex with about a 4 mile reach. (Yes, I said 3 above, but I'm adding a margin of error due to terrain and such.)
Clearly, I can test option 1 really easily, and if that does the trick, I'm home free. Both options 2 and 3 will require a fair amount of drilling. If option 1 fails miserably, are options 2 and 3 worth the effort?
Thanks for any advice. I'm a newbie, but I learn pretty quickly.
