Antenna for non-rotator ground station


#1

Hi, I am new to SATNOGS. I would be happy if you could help me with my questions. Which antenna should I choose for the non-rotator station for both VHF and UHF bands for CubeSat communication? Can I use a turnstile antenna? And also the link where I can buy online?

Turnstile is ok but why not build a QFH? I’ve tried them all and found my home made QFH antenna the best. I use them for VHF and UHF with a couple of LNA4ALL pre-amps.

Simple answer is yes you can use a turnstile and quite a few (including me) do use them. I have a VHF and UHF set of GS’s, just like what you are thinking about but the difference is I have a nice (Wimo) turnstile for the VHF and an el cheapo UHF (eBay - none to link to but they appear every now and again. If the TA-1 is a bit expensive then I started with the AMSAT Funcube antenna.

I think the cheaper ones are from a similar source and stanislavpalo130 on eBay is a good source of reasonable antennas

Hope this helps (you’re bound to get a bunch of other opinions too :wink:

Is there any turnstile antenna that can receive both 137 MHZ and 430 MHZ range satellite signal in one antenna?


#5

Is there any place where I can buy online instead of home made one for VHF and UHF bands?


#6

I’ve seen a few dual band ones on eBay in the past. Not sure how well they perform. Wimo also supply QFH antennas


#7

Nagara also sell commercially made QFH antennas (QFH 144 and QFH 430, with a QFH 243 that bundles one of each on a short cross-boom).

My main purpose is to communicate with cubesats in VHF and UHF without rotators. How about this one, does anyone has experienced with this antenna or is it okay if I go with this dual turnstile antenna?

I would be happy if you could suggest the right cables and preamplifier.
