is DC ground the same as earth ground?

if everything checks out (I am going to check the coax and antenna
tomorrow) to be OK what would be my next step...

Hello Jim,

The A99 should have a good DC ground reference. It's sounding like the
internal parts were fried. The only time I have seen this is with high
power being fed into the A99. Go through the system. Check your coax
and connections. You may have a short in one of them. Disconnect the
coax from the antenna. use an ohm meter to measure from center to
shield of connector. This must read infnity. measure from center to
center and then shield to shield. In both cases it should be less than
1.5 ohms. When you connect the coax back onto the antenna, you should
have around 2-3 ohms through the antenna.
I hope this helps....
