I was wondering about the Lindenblad antennas. I live in an area where winter conditions aren't always conducive to going outside and working the Sats and eventually want to have an Az/El system but until the time and money are available I was considering building this style of antenna. Does anybody have experience and/or recommendations?
Thanks Jerry W4JWC

Agree about the "Eggbeater" style. When I first returned to the sats I homebrewed a couple and they worked fine. But even better is a Moxin style which provides gain and circular polarization. See Larry Cebik"s article in August 2001 QST. I built these and they worked great for the LEOs. Great for portable too, as are omnidirectional. Kevin/W3DAD

Fred,
In addition to Kevin’s idea, you might want to consider some home-brew “eggbeaters.” When I first started on the LEO’s, they worked fine to get into the birds, including the ISS. Won’t outperform a beam many times, but they are efficient for the cost.

Hi Fred, If you're working the current crop of LEO sats, then you don't need an AZ/EL setup. Just AZ will do with the Arrow antenna set to about 20 degrees elevation. I control my HD-73 with the Easy Rotor Controller (ERC) using SATPC-32. Very simple and works well with the Arrow. Get you started without too much invested. Kevin/W3DAD

Please excuse the newbie. I have been receiving signals on SSB, CW, Packet, and FM via just listening for a while now. I am newly back into the satellites as I used to work the high elliptical orbit birds years ago. Let my license lapse and just got it back and upgraded. Now
getting
the satellite bug again and have really tried researching on the net but
am
a bit frustrated by the paucity of az-el rotors available. It seems that there are primarily the Yeasu G-5500 type at $700 to $800 or more or make your own and really no in-between. I am looking to have a permanent installation that could track both az and el and preferably be controlled by SatPC32. I am thinking of starting with a small single antenna with both 2m and 70cm on it (i.e. Arrow or other) which would present very low windage. When I initially got re-interested I was imaging a cheap
solution
with TV rotors but I don’t see any folks doing this and I would prefer
not
to have to set my antenna solution up every time I want to work the satellites. Am I missing something or could someone point me to an
article
or reference that I am not aware of? I really appreciate all of the collective experience in this group and thanks for your time! I am
using a
Kenwood TS 790A without the 1.2 Ghz installed. Best, Fred Castello, KF4FC _______________________________________________ Sent via AMSAT-BB@amsat.org. AMSAT-NA makes this open forum available to all interested persons worldwide without requiring membership.
