Hi Ken

Further to my last about a narrow vertical beamwidth.

Is a quick and rough modeling of a 16 el collinear. Note the half power
beamwidth of only 4 degrees...

Cheers Bob

Wow - that's sharp! It explains why I lost the signal in my front yard.

How about this version?

I just built it out of a coat hanger, soldered to the old coax
feedpoint from the last "experiment". It performs pretty good
but I calculate 2.14db of losses in the line. Something my
back of the set antennas don't have to deal with.

What about expanding the above antenna?
