[AK-VHF] RSVP: 6 Meter Antenna Test on Tuesday Evening

Brandon,

Don't get me wrong, a simple horizontal dipole is 
good start and useful for near omni-deirectional antenna in an urban setting.

I worked many stations on Es as far as KY and TX 
with my simple 3-element yagi.  It does not take 
up much space (mine has elements spaced 32 inches 
so only a little more than 5-foot long.  I 
converted a 72-MHz DB Products commercial antenna 
by just lengthening the elements.

Ed
If I hear you I will transmit 80w (max power with 
my amp).  I've worked KL6M with it.
