[TowerTalk] WARCdipole above a tribander-which direction?

[Bert Almemo]

Hi Kathy,

You don't have to worry about spacing between the tri-bander and the D3W. A
friend of mine put it on the same boom as the tri-bander, between the driven
element and the reflector, with no problems. Minimal interaction. Makes for
a very compact installation. Good luck!

This note earlier got me thinking.
I'm about to put a Cushcraft tri-band WARC band dipole above my HF
tribander(EX-14). Can space it about 6' above. Oddly, Cushcraft only
mentions to keep it spaced that distance from VHF antennas, but nothing
about space/orientation to a HF antenna. I'm inclined to put it 90deg. to
the tribander, figuring, less interaction AND less strain on rotator/tower,
as it will be a counter force with the wind. Any counter arguments?

I
 started an off list discussion with Peter about this.  I did almost exactly
what he proposed only 6-8 weeks ago, except I used a C3SS and the total
stack height is lower.  In my case, I looked at adding the 40m  kit on the
c3ss, but the increased turning radius would have been an issue (ask W2GD
how close I am to the property lines)

When it
came time to decide parallel to the boom, or parallel to the elements, we
went with "rule #1" (do what the Mfg says), and we called Force 12. They
said "5-10 ft between antennas?  Put the elements in parallel", so we did

System has been working FB, so I can't complain
