[amsat-bb] eAntenna

[David J. Schmocker]

Ray:
I own one InnovAntennas LFA and in my experience the design is excellent
compared with traditional yagis I have owned before.
ŒExcellent' is defined as very low noise due to the drive loop (view the
antenna azimuth pattern and it shows!).   For a given boom length, LFAs
are about 0.2dB behind conventional yagis but the lower noise and broad
banded nature of them makes them SWR-stable and high-performance in all
weather conditions.   However what I will never agree with is the square
boom idea.  Indeed it makes antenna assembly a breeze, but I have
home-brewed my own round booms because I need to be able to manage the
wind load.  Probably a UHF antenna (with an extra robust rotor under it)
will be a non-problem.
Good luck.  Very 73,
Dave KJ9I
