I'd like to mount several antennas at more-or-less the same spot:

- wideband receiver (thinking of a Diamond D130NJ)
- broadcast FM receiver
- directional TV receiver (Channelmaster 4228)
- aviation band
- 450MHz commercial band
- 2m/70cm transmit/receive (Diamond X50NA)
- WiFi
- satellite radio receiver

I know putting them close to one another isn't ideal and may cause
interference, but I'd like to start there and see whether it's a
problem. None of the transmitters will be high power.

I plan to put them on the gable end of a wall, with mast(s) that go
above the roofline. The mast(s) need to end up about 18" away from the
wall to clear the roof overhang, and I'd like to make as few wall
penetrations as possible.

My ideas include:

- mounting a couple of pieces of uni-strut horizontally and using
regular stand-off mast brackets
- using a short piece of tower, attached to the wall, and some sort of
brackets to hold antennas off of that.

Any other suggestions that are maybe obvious to people with more
experience installing base station-type antennas?

Thanks,
Heath
