Telescoping mast.....
Hi,
I do believe you COULD find some telescoping TV mast, some to 40'. But, the bottom
section is at least 10' long with other's inside. They also won't be "cheap".
The "trailer" (at least 12 feet long) isn't going to be cheap either.
What I think you're envisuoning is a pull-behind trailer for "outings" and to be able to
either monitor or operate as either a CB'er or Ham while away from home. Certainly,
depening on the vehicle you drive this could be done with a 12' trailer and some 10' 6"
sections of swagged, cyclone fence top rail. I recommend assembling it, one inside
the other and on up. Then, taking some heavy, stiff, flat, metal bars on opposite sides
drill bolt holes above and below the joints and bolt it all together, when you have
"arrived" at you destination. Then, guy it off with strong rope, mount the suitable
antenna and "walk it up!" When you "break camp", just reverse the process.
If the antenna is light enough and you have enough rope guys, it possible to get 60'
up...Small VHF or UHF antennas ONLY. You don't want to try in putting up a 10 meter
yagi or quad this high up, LOL!
I have a 2m/70cm "J-pole" up at 30' using this method. Soon, I'll have a "Slim Jim"
antenna (GOOGLE) up at 60 feet for both VHF and UHF as well. These antennas will
be for receiving ONLY though.
Even with the 2m "J-pole" at 30', I can hit an 2m FM repeater "solid" 70 miles South
of me and can hit one 130 miles South of me, marginally. The wind has to be blowing
just right for the one in Alexandria, LA. Ha ha ha ha.
Now, all I need are some good, omni-directional, horizontal 2 meter & 70 cm ssb
antennas for local work and a good long-boom 2m & 70 cm quads for ssb long work.
These also can "double" for scanner antennas when not in Ham use.
I really DON'T need to try and put up any 800-900 mhz antennas. I get great reception
on my PRO-95 with just the short, 2" BNC "ducky" when, I carry it on my hip OR if mobile, I have a 12" scanner antenna/ RG-174U coax. Even WITH the "ducky", I'm able to hear
the LA. State Police down in Mansfield, LA (40 miles), South; Longview, TX (60 miles),
West.
I *do* have an old, 40', telescoping HD, Tv mast. It's reserved for the 25', wooden,
long-boom 2 meter FM Quad I'm putting up. No telling HOW far I'll be able to "hear"
and talk then. Bwahahahahaha!
