A very interesting item was brought up though. You question the
Invacom with the Fortec dish and elevation. I also have a Invacom on a 80cm Fortec dish and had to raise declination 5 degrees to get signal. A discussion was going on concerning adjustment on dishes and the preliminary conclusion was that the Fortec dishes (little) may be using some form of universal scale mount. Accurate for some and not for others.
I am wondering now of those that reported having to raise declination 5 degrees or so are running the Invacom lnbf.
