I have most of a Cushcraft 20-4CD, but am missing one director. ?I can
probably buy the missing element from Cushcraft or homebrew same, but I would
like to get it up on my 94' tower this week as a 3 el wide spaced beam
centered around 14.150 for both CW and phone. ?I would prefer gain at the
expense of F/R. Boom length is 32 feet. ?Antenna will be used mainly for
contesting. I would like the elements equally spaced or close to that.
?Cushcraft element lengths for their closed spaced 20-3CD ?el yagi (20' boom)
centered on 14.100 are:
REF- ?431 1/2 inches
DE ??420 inches
DIR ?403 1/2 inches
My ARRL Antenna handbooks give the following dimensions for a wide-spaced
approximately 32' ?(.2 wl equally spaced) 3 el yagi centered on 14.050:
REF- 422 1/2 inches
DE- 401 3/8 inches
DIR- ?381 3/8 inches ?
I am surprised how different the above specs are and would appreciate your
comments and confirmation of the ARRL Antenna Handbook specs, if possible.
?Unfortuately, I don't have the entire CC yagi documentation so can not give
you the element tubing dimensions, but maybe someone else can supply that
And does anyone think I would be better off with 4 elements on the 32' boom?

I've spent the past 2+ hours using AOL 6.0 trying to resubscribe to Towertalk
going between AOL 6.0 and "AOL Everywhere" and finally going to a different
computer to send this message since I could not paste from AOL 6.0 to AOL
Everywhere, and Towertalk would not accept a post from AOL 6.0 Does anyone
know if Towertalk will accept posts from AOL 7.0 I hate to upgrade again and
have even more problems. AOL will not let you downgrade to AOL 5.0 which
works, and is on my older computer which I'm using now.
