T-band mobiles reception

[Joe1123]

Hi .. is there a trick for pulling in what is (probably) a low power T-band frequency? There's a frequency in the 470-512 range a business uses for mobiles that I can't pick up at home (probably 10 miles distance as the crow flies). I'm thinking they are using low power because I only pick them when I'm probably within 1-2 miles of the place. ... Would a T-band antenna (470-512 MHz) make any difference? ... I really don't have the option for an outdoor antenna. Thanks for any info/tips etc.

If they are not using a repeater then the range is going to be very short. Most repeater antennas that repeat 5 watt UHF walkies are over 300 feet high. I have a plant here in my town their antenna is 30 feet they cover about 2 miles from the plant.

Yup - I've even encountered some DMR trunk systems (with repeaters) where you have to be within a very short distance to hear it. The system serves a single complex/facility and they really have no reason to be heard much farther than that (even though this is not typical).

For mobiles, you just have to be close.

If you are in Rochester, NY as your profile says, I doubt it is t-band....at least not legally. The only T-band permitted area in NYS is the NYC area.

Hi, not sure what you'd call it then ... frequency is in the high 470s, nearly 480. .. But really I'm wondering if one of those antennas meant for 470-512 (rubber duckie) would make any difference. My guess is probably not.

For a system to work 10 miles or more REQUIRES 300 FOOT TOWER. List who you are trying to hear so we can look it up. We all know you can go to Walmart look at the FSR and they say up to 30 miles that just will not happen walkie to walkie it has to use a repeater.

What Frequency / Agency ?
As others pointed out, based on your profile, T-Band is not a valid allocation in your area...

I just did an FCC ULS search from 470-490 in Monroe, Wayne, Ontario and Orleans Counties and there are no licensed hits (as expected).

Assuming flat earth...which of course this planet is not....Ground elevation and HAAT is as important as the tower height.

That is why I posted a link for the new member to read. The last tower I put up was a 800 footer. Has Public Service 800 UHF and VHF mounted at the top also rental 800 and UHF.
