Hi: i am looking for a portable Turnstile antenna for receiving NOAA Wx Satellites...We do a lot of camping in remote areas and it would be great to be able to receive the downloads...Plus it would just be fun! Does anyone know of a source of a portable, collapsible, carry-able Turnstile Antenna for the 137-138 frequency range? Thanks,

Steve

AMSAT-UK sells one:

It works OK in the 2m ham band, but was designed for 137 MHz.

Just to confirm: It will be adequate for the NOAA satellites? Thanks again!

Yes. The antenna sold by AMSAT-UK is actually tuned for the 137 MHz satellites. Here's a web page from the antenna's German manufacturer:

How does it do on 2m for receive and transmit for the sats?

As I have mentioned on this thread, the AMSAT-UK 137 MHz turnstile works OK for receiving satellite downlinks in the amateur 2m band. As for using it to transmit on 2m, I have not tried that. Since the antenna is designed for 137 MHz, and I don't have an antenna analyzer to check its performance for transmitting at 2m, I use this solely for receiving.

Does the AMSAT-UK antenna break down easily for portable use? Thanks again for your information and patience! I do not care about TX...Would only be used for receiving WX and other downlinks from satellites...

Yes. The 8 horizontal elements easily screw into and out of the center of the antenna. I have used mine on a portable mast and tripod for demonstrations.
