As frequency decreases, so does the importance of keeping the dipoles
exactly above one another. This is why you can get away with mounting
the bays of a LB array around a smaller tower (like Rohn 25) and still

Do you recall if it was a dipole or folded dipole?

Lots of comments on the unidirectional pattern which I suggested might
not work well.
Any comments on having the elements on one side of the tower right on
the leg?

Anyone have any info on a Regency Micro-Comm U10R ?
Especially the pinout of the 15-pin Molex plug?
I have one here and was wondering if it was worth resurrecting.

I remember seeing a vertical dipole from one on the amateur antenna
manufacturers that was designed to bolt onto your mast or tower leg. I think
it might have come in a kit of 2 or 4.
I thought it was Cushcraft, but I couldn't find it. Does anyone have any
idea what antenna I thought I saw?

Thanks for the info on Cushcraft, although I thought I'd run across the
antenna I'm remembering within the last couple of months (current
production).
I'm looking for something that I can mount on the mast of my home tower,
interwoven between other antennas on the mast. (Obviously with

Cushcraft made a 4-pole array for 2-meters and for 440. Neither were
particularly good antennas. They were gamma-fed dipoles with a connector
that was nearly impossible to weatherproof. Lots better
FYI, MFJ just purchased the Cushcraft antenna line.

I'm sure someone on *this* list will be able to correct me if I'm wrong,
but I think you can mount virtually any of the dipole type antennas on
the tower leg as long as you're not looking for a 360 pattern. An offset
or figure-8 pattern, though, no problem. In fact, I've done this for
21 matches
