[Antennaware] HF Colinear Dipoles

[Gedas]

Hi Karin. I am no expert but I will try to help out any way I can. I did 
some modeling and then constructed a pair for HF and they really worked 
well. I documented the setup in one of the ARRL Antenna Compendiums, 
don't remember which issue but I can find the PDF if you like. 73
