[K3PZN-List] The Cookie Tin Antenna - QST oct 2013 p 39-41

Mon Oct 14 22:39:36 EDT 2013

Hello Jim and everyone ...

i should have changed the subject line instead of just using same
subject.   Kerri and I have been doing some mountain topping so I have been
taking two rigs and two antennas   an eagle one vertical capable of
different bands and a homebrew diapole cut for 20m.  noticed that I needed
to maybe have the antennas much further away from each other than I had.
