Has anyone tried working FO-29 with egg beaters or other omni directional array? I have plenty of power and a good preamp. I have yet to put my yagi's together (after my last move) and wonder if I can cobble together something that will work.
Hi Joe
In answer to your question YES.
Managed a contact through it last week at a range of 2700Km using a tri-band colinear 10m above ground, no pre-amp and a Kenwood TS2000 running 50W. Location here is 10m above sea level.
Not easy but it can be done!!
Regards
David G8OQW

Joe,
Made three contacts on FO-29 on CW with 25 watts, ground plane antennas for two and 70 cm before I had to move to a senior building and no outside antennas allowed ;-)

Hi Joe, K4SAT
I tried using a home built RHCP Quadrifilar Helix for 70 cm and it works great beginning with FO-29 about 10° above my horizon.

Hi Joe,
yes, I had tried to listen the FO-29's downlink with QFH-antennas on several arrangements and I noticed that the QFH is the most reliable omni Satellite-antenna. The downlink signal was superior in comparison with other omni-antennas. (My QFH was based on *excellent* articles of I8CVS & W3KH respectively, with infinity baluns).
The most important point (as usual) it's the length of coaxial between QFH and Receiver. On my experiments onto my roof by using just a few feet of cables, the QFH was pretty good for FO-29 reception. The problem began when connected with my long-long coaxial cable up to my shack, even in case which I used good quality cable. It's obvious that, the QFH with long coaxial needs a preamp, anyhow. But in this case, you need hard work in order to be able to achieve the best result for good reception.
However, even if QFH is the best Satellite omni-antenna, my experiments proved me that for Linear birds, like FO-29, the QFH is worst than any small UHF-Yagi (ie 5-7 El). The superiority of Yagi antenna is obvious especially in weak signals (Q5 upto 1-3 S Unit). On the other hand, for FM-birds the QFH is good enough and that probably has to do with limiter-stages in FM-mode receivers. Just keep in mind.

Hi all, Just something else to try. A 1 wavelength 1 Turn QFH. best gain @ 30 degrees instead of 90 where you do not need it.
