Could the problem be something else? The reason why Im asking this is because the ham radio system that we are on is connected to State equipment. Namely, CDF and law enforcement through a combiner on the RX side. The TX on the machine is working great but the RX is very shotty.
ps. This is not the author of the original post. We just happen to be experiecning the same problems after a lightning storm and I didn't want to start a new thread. (Keep all good info in one place for both to read)
Thanks

Fred,
Since you imply that this is a two-antenna system without a duplexer, the
only item that you have not changed is the RX antenna feedline. Before
assuming that it might be defective, use a TDR test set to sweep the cable.
Also check any jumpers or adapters that may be in the receive path. Since
repeater coverage is primarily limited by how well the repeater can hear the
stations in the field, check anything and everything that is associated with
the receive path.

Subject: [Repeater-Builder] Problem of repeater after lighting striked RX
antenna
Hi..
Recently, the repeater I was maintaining was hit by lightning. The
whole antenna was gone, and our turbo fans were fried..
However, luckily, all the radios are still on..
I've changed the RX antenna, the pre-amp and the lightning arrester.
However, when we tested, between two points, let's say A and B.. A is
nearer to the repeater and B is further.. when A calls B, B could
hear, but when they reply back A couldn't hear..
What could be the problem? I've changed the RX radio, but still the
situation is like this.. it seems that the coverage of the repeater
is smaller than before..
Is there any thing that i should check also or changed.. What should
i do when lightning strikes..?
Thanx
Fred
