Humvee's in Louisville
« on: September 23, 2020, 12:32:19 PM »

I hope this subject  would overlap into emergency communications. I just saw Humvee's streaming into Louisville. It would appear they had low band antennas.
Would they use low band in a city?
Or could they have radios that could also use the low band antenna for vhf tactical use.

The military uses 30-50 MHz FM for tactical operations. HF SSB for longer range requirements.

Why use low band? They don't use repeaters....

My guess.

I think "back when" (late 1940s and early 50s) it was decided that low band VHF radios were easy to build, easy to maintain, fairly rugged and had adequate coverage.  And, later, since the equipment was replaced piecemeal instead of all at once, the new stuff had to be backwards compatible with the old stuff, so the "low band" became almost a tradition.  Now, there are HTs out there that can do 30-512MHz in various modes and the frequency horizons can expand.

For tactical communications, no more range than needed is good.  More range means more of a chance of being heard by "the wrong people" and even if the signal is encrypted, the presence of a signal can provide useful information.

Thanks,
it would be naive to think they are using only low band in a city type situation.
I'm pretty sure they have some tech laden HT's on vhf. I guess they make the military humvees with every antenna they think will be needed.
