I have a chance to buy an Explorer 40-foot telescoping tower, which from
the very brief description I have sounds like it might be useful for Field
Day and CAP exercises, but I can't find anything on the net that describes
it.

It comes with something called an "undertire" mount, which I assume means
a tower base with a plate onto which you drive the tire of a vehicle and
park it there, to hold it down.

I googled "Explorer tower" and got nothing. The owner reports he bought
it from AES but there isn't anything about it on AES's website either.

Anybody know what it might be and where on the net I might be able to find
some information on it?

Thanks...

Hi Rick,

Some years ago, I fabricated a 40' tiltup/rotatable mast from common 1¼"
plumbing pipe specifically for FD. Yes, it needs to be guyed (two guysets).
The mast supports a Cushcraft A3S 20/15/10m yagi. The top guys serve
double-duty as 80 & 40m inverted vees (80m is a 4-wire cage, and covers
nearly the entire band w/o a tuner).

Some metal fabrication is required (drilling & light welding) but it's not
too involved. A single person can assemble & tilt the mast up/down though
more hands makes it go faster. Some photos and a video clip are he

me know if you need more info.
