T-Mast hardware

[blantonl]

I just finished building a new home in San Antonio and I'm looking for a source of antenna mast hardware that is appropriate for an eave installation for two scanner antennas.

I believe I've found some decent hardware that will support a single mast installed on the eave, however I'm looking for a source of "T" mast hardware that will allow me to install two antennas on a single mast, like below

Thoughts? Anyone know of a vendor that provides this type of T Mast type hardware?

Also, just for reference, I'm planning on installing a DPD OmniX antenna and UHF airband antenna (not sure of vendor yet)

I personally would build something using cross over clamps such as these....

I would use aluminum pipe also with stainless and/or galv hardware. The omni is a pretty lightweight at about 2 lbs, and as long as your horizontal pipe isn't real long the T should be fairly rugged.

Yes a crossover plate is what you need. Remember you'll need a way to attach the antennas to a horizontal pipe, as most antennas are designed around vertical mounting.
Like this (example, this is probably too large for your masts). http://www.tessco.com/products/displayProductInfo.do?sku=467818

Hams use horizontal booms for mounting multiple satellite yagis as well.

I occasionally use 1" steel water pipe and the thick wall aluminum equivalent with Nu-Rail or Speed Rail fittings. These come in T, right angle and many other shapes. Here is a link to the T fitting and right angle that will make exactly what you describe. Some versions have two allen set screws per pipe which is great.

I prefer to use the aluminum equivalent of 1" steel water pipe which is about 1.3" OD and about .125" wall thickness, which is very strong but lightweight. this setup is plenty strong for an 8 to 10ft wide cross arm with moderate size antennas up to maybe 10ft tall.

And since its Lindsay asking, I have one of these that would fill your UHF airband needs if you want to discuss:

Many thanks everyone for the feedback and pointers - this is exactly what I needed.

pcrguy: I'll give some thought to the UHF discone - I'm leaning towards a dedicated 700/800 MHz antenna along with the OmniX.... I've got two runs of LMR-400 coax run to the eave on the house, but I've got 3 runs of LMR-400 to the back of the yard where I have a nice greenbelt to put up antennas... we'll have to see....

Thanks!

A small flat aluminum plate ate the top of the mast secured and 2 NMO or your choice mounts on the plate.
