Now you are talking.  I installed a 24dbi grid and an 12dBi Omni at a Super
8 and it did the same thing.  I actually mounted the antennas on top of the
Local TV antenna and it knocked out all of the local channels. (During the
World Series)

I basically put 20ft between me and the TV antenna putting me beside the TV
antenna not infront or behind of it and that worked. (The orientation of the
TV antenna was north to south and I created a setup to the East of the
Antennas orientation) It has not interfered anymore.  You may need more
distance between you and the TVs' or Antennas on the Cable TV antenna.
Maybe even turning down the AP's but that may defeat the whole purpose of
getting you on the tower in the first place.

Sorry for not being more descriptive.....

There are two places: First, I have my AP on the top of the cable TV
tower. I also have a point to point shot (another APPO) shooting about 1
mile down to another tower in town. That tower in town is at a store
that sells televisions. I have the other side of the point to point link
there, as well as another AP using an APPO.

When I fire up the APPOs at the television store, it completely knocks out
channel 7 on his televisions in his store. But when I turn on the APPOs on
the cable TV tower it knocks out channel 7 for the entire town (the town
gets channel 7 through their cable TV, but I'm assuming the cable tv picks
it up through the air at the tower I'm sharing with them and retransmits
it through their cable.)

Hope this helps, and I'm sorry I wasn't more clear at first.
