wish i could get permission to install an i.AM Tx and ATU here...
This is what I would do.
Meet with the manager of that tower. Explain to them what you would like to do, describe yourself as a public service with scarce funding, and ask if they will host you as a public service.
Do that. If you are turned down, sorry. But right now, all you know is, you haven't asked.
If I was the tower manager I would put you on and use you to promote space to high-rent clients, and simply conceal the fact that you are a "guest." Your antenna makes the tower "appear" like a big success.
Get in the game.
MOREOVER, if you are turned down, act totally unconcerned, and tell the manager you will check again in the future.
In one month call him again and request a meeting. Start from the beginning.
Eventually he might give you a spot on the tower.
what do you guys think? since the i.AM was certified with up to a 300ft coaxial cable between unit and atu, you think the atu would pass an elevated install such as a 100 or so ft up this tower?
"since the i.AM was certified with up to a 300ft coaxial cable between unit and atu, you think the atu would pass an elevated install such as a 100 or so ft up this tower?"
Well considering even the iAM unit and the ATU, and the typical setting for which this is used, I really cannot say for sure. I mean there is not a 100 foot tall tower or mast in everyone's yard or on homes for sale. At most one might see an external ATU mounted on a real estate sign with the supplied 25 feet of coax running to it, which would most likely also be serving as the ground counterpoise to that of a ground radial system was there already.
I would contact the FCC and give them the certification number of the unit so they know what unit your referring to, and then tell them about the 100 foot tall tower and the question of this certified unit being ok to mount up there or not.
Worst case is they say you cant.
