    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

Anybody know where I can find a cheaper option
for the mast to mast mounting clamp in the pic
below? I need about 6 of these and can't justify
spending $120 + just for clamps
Even something that compares will do.
I will be mounting 3 antennas onto a Rohn tower
without a top section.

I would use stainless steel hose clamps, they work great and will hold up surprisingly large antennas. I use two clamps on small antennas like Discones and short lightweight verticals. Three on larger ones up to about a Comet GP-9 series and the aluminum base of that antenna will break before the hose clamps give way. I've even held up 21ft long and heavy Super StationMasters with four large hose clamps and it was very strong.

If you look around your town at huge street lights that hang over several lanes of traffic, you will find similar but larger versions of hose clamps holding all that together. They also try to self center the antenna better than a couple of U bolts.

If you are mounting them on the ends of a tower section, don't plan on any being used for transmitting unless you want some expensive repairs to your receivers.
Even if the radios are completely different bands?
1 antenna (Antron 99) on 10 and 11 meter on upright leg of tower
1 antenna (Comet) on 70 cm on upright #2
1 antenna (Arrow Open Stub J-Pole) Dual band VHF / UHF on upright #3 with
about 6 - 8 feet vertical separation

Almost never would the 70 cm radio and the dual band radio be
on at the same time and never-never will both be on when
transmitting.
Would the 11 meter radio damage the 70 cm or the dual band
VHF / UHF being that far apart in frequency?

Antenna spacing

The general rule is the farther the better. You would only have to forget once to blow out a receiver you didn't turn off. There are several articles online that will give you a good idea. The general rule is at least 1/4 wavelength. Amount of power and wavelength varies, and without specific measurements, you will be taking a chance with your equipment.

Very good jaspence. Guess I'll be putting plan B into
action. Thank you

prcguy. Gonna go with the hose clamp idea. I never thought
of them as being strong enough to hold, but you would know
this better than me. I ordered 20 online. Also I ordered a pack
of 5 T-Bolt clamps because they are thicker gauge metal and
look stronger. Gonna give both a try. Thank you
