RE: [TowerTalk] antenna spacing

[Jeff Chambers <jeffchambers@cableone.net>]

Thom,

On my tower I put my 440 & 1296 yagis (ATV) on the ends of a 6' cross 
boom located almost at the top of the mast. This is about 6' above my 
Hygain EXP-14 (HF). No interaction noted. I used the Handbook to 
calculate the windload of the entire apparatus, which ended up being 
just a bit shy of 14 sqFT. The feed lines go down the length of the mast 
to below the HF yagi, and then the rotor loop begins. If you would like 
a picture to better explain it let me know.

Good luck es 73,

Jeff	KK7MQ

Subject: [TowerTalk] antenna spacing

My 50 foot AN Wireless tower was installed last weekend and sometime in the
near future (probably when it is snowing like crazy outside) the antennas
will be installed.

I am planning on installing the following

Cushcraft A3
Cushcraft A50-5
Cuchcraft A144-20T
Cushcraft A719  432 yagi

guess you could say I am a Cushcraft fan.

I have 15 feet of mast above the thrust bearing to play with.

I am looking for suggestions on spacing these antennas.  I might be willing
to sacrifice the 2 meter or 432 if necessary

thanks

73

Thom WI8W
