[UK-CONTEST] HF Beam/WARC dipole on same mast

[Darren G0TSM]

Mount at 90deg, you soon get used to the needle on the rotator 
controller being one leg of the dipole.
If you really want to mount it parallel to the driven element of the 
yagi try shorting out the feed point of the dipole and then mount it 
about 8-12" away from the driven element. The coupling should resonate 
the dipole, if it doesn't if hasn't cost you anything. i remember trying 
this but I didn't have a good enough swr dip on 30M.

Mounting the D40 parallel to the tribander's driven element didn't upset 
any patterns or swr, that antenna worked brilliant.

Here's what I took down in 2001, a Create 318B (Now at C5DXC) a 
Cushcraft D40 and a Cuscraft D3W

Brings a tear to my eye ;-)
