Hello there!
I've been having trouble with my Arrow Antenna on the FOX sats. It seems that when I point my antenna at the satellite, say on a 70 degree max elevation pass, it doesn't receive it. But when I point the antenna at the ground, it comes in very clearly. Towards the end of the pass, I start receiving it again because I'm pointing my antenna near the horizon. At this time, I make all of my contacts. What could be the problem? I checked the elements on the antenna and they aren't mixed up. Thank you!

Total guess, but perhaps a connector issue on the feedline? To rule that out use a SWR meter between the rig and antenna and see if the SWR changes when you are pointing things up high.

Are the elements installed on the boom backwards? :0
Shortest element closest to the satellite.
Too obvious?
What antenna problem causes a null off the tip of the boom?

I have had one Arrows but three duplexers. Nice antenna, light weight but not too forgiving if it gets bounced around. I am now using an Elk and am quite happy with it. No more duplexes to fail because I am rough on my toys.

When the satellite is directly overhead with a vertical antenna that might be tough to contact. Perhaps pointing the antenna at the ground is causing the signal to bounce and reflect. 73 Robert MacHaleKE6BLR Ham Radio Licensehttp://spaceCommunicator.club Supporting Boy Scout Merit Badges in Radio and Space Exploration

Many good explanations have been offered, but I'm surprised no one has suggested the most obvious one...
most of our satellites have, after all, INVERTING transponders!

I really hope this is not another trick question, if not, better get a new antenna, radio, and/or coax - seriously. A 70 degree pass of the Fox-es and a clear view, their strong signal be received with a random wire. On such a high pass, normally get 4of9 bars with a rubber duck and 8of9 bars with a 2 el yagi !
