Hi all,
I'm considering building or buying a 5 band HF quad (10 thru 20 meter).
There's a local antenna company, that markets a model that has a single
feed for all the elements from 10 to 20 meter. You can see a picture of
it at http://www.gbanttow.nl/GBFGQUADmessung.htm . I'm interested in the
following:
1) Isn't the radiation pattern of such an antenna severely compromised
(side lobes etc.), because of mutual interaction of the radiators?
2) Can anyone tell me from experience if this concept works or not?
3) Has anyone ever modeled such a quad with a single feed using antenna
modeling software?
Thanks for the assistance!
