« on: November 26, 2001, 08:28:49 AM »

I have come across a 5 band vertical antenna and need some help in indetifying it.  The antenna has four closed loads (not open air coils).  Is about 25 ft long, has a Cushcraft style feed point(simlilar to the ones on the other Cushcraft verticals such as the 2/6/10 mtr Ringo's).  With 3 Approx 25 ft long radials the antenna will tune 80 or 75 mtrs, outside the 40 mtr band (7459-7500), 20 mtrs, 15 mtrs (below the band), and 10 mtrs.  I have tried to find info on the net and Chushcrafts site as well with little success.
Thanks in advance to those who can and do help

I'm afraid the description isn't really enough.  Can you take a digital photograph of the antenna and post it where we can look at it?

HI Sandor: Sounds like a Cushcraft R5 to me. It should have a small plastic box at the feedpoint. If it does try Cushcraft's web page again, looking for specs on the R5. I used one with good success for several years, and a friend is still using mine. But don't put more than 300 watts CW or 500 watts SSB into it or you will fry a trap.

Sandor,
It sounds like a Cushcraft AV-5.
That is a 80, 40, 20, 15, and 10m  1/4 wave vert.
I believe that it had a small capacity hat about 2/3
of the way up the antenna... Not sure... it's been a while since I've seen one...

Try contacting Cushcraft...

Takes a look at the R-3 on the CushCraft web site.

Sounds like the 15 band version (1/4 wave vertical)

They added traps and height to the R3 for 40 meteres (R4) and 80 meters (R5).

The R5 did not have a tuning box, but I believe there was a rating on the coils.  Call or send Cush Criaft digital photo and ask for specification and tuning sheet (spacing between traps adjustments)
