Rick, I ran eggbeaters in my attic before installing an el-az system there. I think the bottom line is the eggbeaters are doable, but they are pretty marginal receive performers below 30 degrees on a good day, and if you compound that by any significant attenuation from the roof or sidewalls it might be a pretty disappointing move. The suggestion to go with something steerable I'd think is really the route to go if you have room. There's a pic of my homebrews on my QRZ page, but if you Google around a bit there are several examples of folks using smaller almost Arrow-sized antennas at a fixed elevation. That takes a lot less space, is simple, and will really outperform the eggbeaters on the passes nearer the horizon. OTOH if you have a lot of room, I think N0JY had a pretty impressive set up documented on the internet a while back that might be worth checking out. In any event you might want to do an attenuation test in the attic on a few passes before making any decisions. I know I'm only losing a few dB when it's dry, but I have no foil-backed roofing materials to contend with, and I did find when I rotate past a large aluminized HVAC duct, I lose gain and directivity for 30 degrees or so. But there is a huge amount of joy in having the system indoors out of the weather, and in my case, out of view of the zoning police :) In ten years - zero maintenance other than to tighten a connector. Good luck. 73 Scott ka9p

Another idea if you have enough room in the attic. Get the azimuth rotor repaired, move your outdoor antennas to the attic. May need to shorten antennas to clear the roof. On Friday, November 8, 2024 at 09:41:35 AM EST, Peter Goodhall via AMSAT-BB amsat-bb@amsat.org wrote:
Rick,
I'm in a single-story house and have health issues, my solution was to keep the antennas low my M2 LEO Yagis/Rotators are only 8ft off the ground and easy to manage and maintain
Maybe worth considering before going the eggbeater route.

Now that I’ve diagnosed that my AZ rotor has failed I’m wondering, at age 75, if I shouldn’t begin to make life a little easier. We do have a one story house but getting up and down from the roof and managing large antennas is getting more challenging and probably dangerous for me.
I have an old pair of eggbeaters in the garage and I’m wondering if anyone has had any experience in using them, or something else, in an attic? This would make satellite operation more manageable for me, shorten my coax run and put me in a position of not having to find younger club members to help, and those are few and far between!
