All about Antennas
(Revised 7-5-18- added article at bottom))
BEST HAM RADIO OPERATORS HAVE GOOD ANTENNAS! You can't work them if
you can't hear them! Does size matter?
Remember you can receive off almost any wire but you can only transmit
on an antenna designed for the frequency you are on.
Just because you can hear someone does not mean they can hear you.

used one for years and it has always produced some amazing results.
Uncle Fred explained to me that he designed it to transmit a lower
than normal radiation pattern.

take some photographs of it and also send them to you."
here is a 6 meter Hen
antenna by K5USS. I made one by modifying the design. I made a
PVC frame and used 12 gage stranded wire. I had a long piece of coax
that had a connector on one end. I attached the open end to the antenna.
I used squeeze connectors to connect the ends of the wire and the
attachments of the coax to the antenna. Put it on top of a 10 ft pole
and set it up next to my chain link fence. It's all temporary until
I test it. See the PDF here.

But this was just for a test.
