WRWK533 Posted August 25, 2023 Report Share Posted August 25, 2023 New to GMRS still. I was wondering why I was having so much trouble hitting closeby local repeaters and didn't hear much of anything. I looked at a topographic map of my area and realized I live in the lowest part of town. By over 100 feet I am in a river valley. I have the option to put up an antenna on my house, but it would only be about a 5 foot antenna extending above a 30 foot roof. What is going to be my best bang for the buck in terms of improving my range? Quote Link to comment Share on other sites More sharing options...
WRKC935 Posted August 25, 2023 Report Share Posted August 25, 2023 OK, explain your current setup. You said you can put an antenna up on your house. But you make no mention of current antenna system, placement, height or anything else. No idea here what you are working with so it's hard to point you in a direction.

WRWK533 Posted August 25, 2023 Author Report Share Posted August 25, 2023 Presently I just have a handheld, UV-5G with the stock antenna. I am willing to put up an external antenna and buy a base station, but not if it's going to bring minimal results given my low elevation.

It’s entirely possible that you’re blocked by the structures and topography of the town. It’s also possible that your radio isn’t sensitive enough. Sensitivity is a problem with inexpensive radios, but being blocked is more likely the reason for your problems. Can you see the location of the repeater? Could you see it if you were higher? How close are you to the repeater? Is there a location that’s on the same line from the repeater, but higher, even if it’s further out? Go for a drive to see. A higher antenna is generally better, but if it’s not, getting a base station isn’t necessarily going to solve the issue. WRUU653 1 Quote Link to comment Share on other sites More sharing options...

If safe (always like to throw that in there), try taking your hand held up on the roof and see if that improves your position enough. You may get an idea if it’s worth putting an antenna up. Also if you know where the repeater is you can get an idea of line if site using a tool like this. Sshannon and WRYG609 2 Quote Link to comment Share on other sites More sharing options...

Are you trying to access the repeater from inside your house with the HT and just the stock antenna? Quote Link to comment Share on other sites More sharing options...

Possibly, I'll need to check. 8 hours ago, WRQC527 said: Are you trying to access the repeater from inside your house with the HT and just the stock antenna?

Try it outside where there are few(er) obstructions. If it works better, a better outside antenna mounted higher with decent coax should help. I'm sure others will pontificate further.

WRWE456 Posted August 26, 2023 Report Share Posted August 26, 2023 I will second the idea of getting on the roof of your house for a test. That will likely significantly reduce the amount of obstructions that absorb/block the signal. Including surrounding buildings. Also make sure to hold the antenna vertically not side ways. Good luck.

WRXW945 Posted August 29, 2023 Report Share Posted August 29, 2023 (edited) Another thing you might consider is doing is: 1. Get a cheap magnetic NMO mount and antenna, something like: https://a.co/d/fL53Q6C . (I know others will say its junk and to get the midland stealth or MTXA26, but were testing and want cheap. Plus you can still use the mag mount and get another antenna. MTXA26 and Midland mag mount links incase you want to pay for good stuff https://a.co/d/2GPfkmc https://a.co/d/1Hoan00) 2. Magnet it to the center of a steel sheet pan and place it in an open window on your top floor aimed at the repeater. (you'll need an adaptor like https://a.co/d/9q4bDhf to attach it to to your HT.) 3. Test if you can hit the repeater. Additionally, there is 18' ish of cable so you could potentially place the antenna and pan on your roof or even mag mount antenna on the roof of your vehicle for mobile testing. Good Luck! Edit: Saw this on Notarubicon. Gotta give credit where credit is due. Edited August 29, 2023 by WRXW945 Forgot to cite source.
