Thanks Chuck about the inverted L idea, I had never thought about that. What
would you recommend for satellite? Turnstile, eggbeater or something else?
Thanks again.
Mike.

The idea is that I want to receive AM and shortwave broadcasts
probably using one antenna. Then, I need to be able to receive 144 mhz
and 440mhz in any direction including straight up for satellites, I am
talking about FM here plus the aviation band in AM. I also want to
receive some frequencies around 800mhz also omnidirectional. I will be
using all of these receive frequencies with an Icom IC-91A. I will
transmit on 144 and 440mhz FM using a Kenwood TM-G707A and a suitable
antenna depending if I want to access a repeater or a satellite. For
that, I have a dual band coaxial type of antenna and I will build
myself a couple of turnstile types for the FM satellites. I just
wanted to minimize the number of antennas I really need.

Thanks for the additional information, Mike. For receiving MW and HF
broadcast stations, a random length of wire often suffices because these
stations tend to employ high power and directional antennas. You might
find that by making all or a portion of the antenna vertical, your
reception of distant stations is improved. An inverted L antenna is
favored by many SWLs. A google search on "SWL antenna" will provide you
with a lot of useful information on what others have used successfully. I
think a "tuner" or impedance matching circuit will be a useful addition,
especially now, at the bottom of the sunspot cycle.

For vhf/uhf omnidirectional reception, your suggestion of a discone should
work well, keeping in mind that it may not be suitable for satellite
reception in its usual orientation.
