And if he is only needing to work Birds close to the horizon, I would not even bother with the elevation rotor. or even tilt the beam up any.
From what it sounds like the beam is not going to be very gigh at all, so just from ground reflections the main lobe will already be elevated.
so shoot for the horizion with any beam you can muster.
Maybe make up a pair of the "Cheap Yagis"
My wonder is without internet, how is he going to keep up with the ever changing Keps?

As was stated multiple times in a very recent thread - omnis for sat work are a poor compromise!! Even a small beam at a 15-degree angle will generally blow most omnis off the roof! Even better would be a pair of beams (one for uplink, one for downlink) on an azimuth/elevation rotor! But handheld can work almost as good!!

We have a newly licenced amateur in DP79. Because they fell a fewpoints of getting their Basic with Honours they do not have HF privileges, their only way to communicate with the outside world is via satellite. Anticipating this possible outcome, that they may not get access to the HF bands, I sent them a hard copy, (no home internet, and its slow and expensive there if you do have it), of the current copy of "Getting Started with Amateur Satellites". As we're heading into the time of year to do any outside work, the most pressing question is what is the best compromise antenna for a base station. Keeping in mind their location, in order to work anyone they'll have to get into the satellites while the satellite is close to their horizon, otherwise the satellite footprint will not cover areas with any satellite operators.
