Down link antenna
« on: March 28, 2002, 11:47:43 PM »

Looking for suggestions for building down link antenna for the fm birds (435) Not worried about a uplink yet I want to listen to a few passes first. I already have a rec converter from hamtronics and hf rig, so I need some suggestions on a antenna (would prefer to build one) and coax. A 440 j-pole just doesn't work, but I had to try it. Thanks in advance

If you do not want to put up a yagi, see the post in elmers about turnstile antennas by KA4WJA  after my post there:  http://www.eham.net/forums/Elmers/18244

Well a J-pole *should* work to some extent ... I've
used my handheld standing in a parking lot to
listen to AO-27 and UO-14.

I ended up building my own "arrow" clone crossed
yagi complete with diplexer for use on the fm birds.
That was a fun little project.

As has been mentioned elsewhere, probably the best
place to start is at http://members.aol.com/k5oe/ ...

Jerry has done a magnificent job of experimenting
and documenting various antenna systems. Look
for his 70cm Handi-tenna for a quick portable solution,
or just build an eggbeater for a fixed antenna.

As Brad posted you should receive something on the 440 MHz LEO's with a J Pole antenna, try when the sats are near your QTH.  I found the SatScape freeware a great satellite tracking program: http://www.satscape.co.uk/
