[amsat-bb] L Band antenna recommendations?

Hi Joe and Jerry.
Thanks, it sounds like Wimo are worth a closer look with both the Helix and SHF designs going into the satellite allocation.
Is the helix reasonably robust?
Unfortunately Jerry, my mechanical abilities are 'limited' but thanks for the idea and HB design that works.

'Soon' is always  a relative term when it comes to satellite construction and launches, but don't sell it and when it's time to dust it off, check it works on 1263.5MHz FM

	The WIMO Helix 23 worked great for me down into the satellite

	Does this mean I may have a use for my L Band equipment soon?

I'm looking for a recommendation for an L band antenna suitable as a
groundstation uplink to a satellite in LEO.
Does anyone have anything they could check for SWR on 1264 MHz please?

Linear polarisation is fine as the receive antenna will have circular
polarisation.  Most of the published data I've seen assumes the user will be
on 1296.

Any thoughts much appreciated

Many thanks
