A couple blocks in a residential neighborhood is normal range for GMRS handhelds. Other factors such as antenna polarization also come into play.

I'm starting a new secret society ... The Friends of Randy. We need a secret handshake and password.

There is also knife edge refraction.

Can't believe I beat this one.

Goes with my comment as well, but you changed other factors for your argument alone.

Does the TD-H8 have part 95 certification?

Yes, further proof that GMRS will become the new CB.

Line of sight also trumps coax type. Even if you lost 90% of power, if you still have actual line of sight, you should make contact.

KAIX 3715

The only perfect antenna is a dummy load, but the erp is very low.

And solar arrays on your roof or neighbors

I'm still dizzy.

Completely depends on the door and shape of the opening. My current work vehicle lets me get the coax out a corner where there is less pinch than along the run. In my experience with damaging coax routed thru doors, the outer plastic insulation and braids of the outer conductor usually get ugly before there is any performance decay

My head hurts

How many GMRS licenses and how many active members here? This site is a microscopic fraction of the GMRS world

There are cheap foreign made amps that cost WAY less than a GOOD mobile unit. But I agree that the UT-72 by itself is the absolute best investment in this scheme. I advise against the amp regardless of its price. The relatively minor increase in clarity of signal to those you transmit to will be of no really use.

Locally, I find more of that from GMRS only licensees that are wannabe hams vs the actual dual licensees

With a few exceptions, ham does not have assigned channels.

The famous bovine derivative of the Schwarzchild metric

Not linked, but someone here reported that there was a locality where one licensee had 5 or 6 GMRS repeater channels tied up. There are such people and if it is allowed, somebody somewhere WILL do it. Ham doesn't have that problem partly because ham has repeater coordination. No such coordination scheme exists for GMRS nor can under current FCC regs.

Without some kind of repeater coordination like ham does, uncontrolled, unrestricted GMRS repeater linking will eventually become a problem. The only saving grace is the practical fars. But once every repeater channel has a linked repeater on a 199 1/2 ft tower ... Be careful what you wish for.

Propagation tends to be across the ground plane. Other than that, there isn't much to consider. In general the outer shielded part of the coax and radio are generally electrically connected to the entire metal part of the vehicle body. An unconnected piece of metal near the antenna may affect it in a minor way, but not likely to be measurable or significantly measurable. It will be generally more practical to make sure the tent rack has strong electrical continuity to the body of the Jeep and each section likewise carries continuity to where the antenna is mounted. Don't over think this, it's easy and simple.

GMRS is 65cm. You are correct, there is no 2m GMRS That comment referred to ham nets, not GMRS GMRS is intended for direct personal use, not an alternate ham band. Something closer to CB

I want my n back.
