WIRELESS SYSTEM for a small college football stadium and officials.

[THE_Rob_Gordon]

Hi guys,
I am in serious need of a wireless system for a small college
football field. I already have the poweramp etc, I just need a
wireless receiver that will work with both a lavalier and handheld
transmitter. I'm not entirely sure of the distance, but I am sure
that 500' will be plenty.

Any ideas?
Matt

1. Get an RF survey done. Find frequencies that are clear and open and see
how clear they really are. Find out how bad multipath problems in the
stadium are.

2. Do everything you can to minimize the distance to the receiver. This
probably means moving the receiver to some point where it is as close
as possible to the officials (preferably within 50 feet).

3. If all else fails, you can probably get that sort of distance with the
Zaxcom system, but you won't like what it costs, and you won't like the
battery life either. You can get 500 feet with the Vegas with directional
receive antennae but I wouldn't want to stake my shoot on it being reliable.

Matt, there are a number of ways to tackle <g> this requirement. As
Scott points out, you'll want to have an RF survey done, preferrably
during a game so that you can see the "background" stuff like TV
stations, and the temporary stuff like intercoms, security, police,
etc. Even still, I would suggest getting a receiver that has scanning
capability, so that you can scan before each game, and during half
time, to catch any stuff that happens to be on at that time.

Secondly, there are two high-powered (250mW - the max allowed for UHF
by the FCC) bodypack systems, the SK250 from Sennheiser and the UM250
from Lectrosonics. These should give you more than enough range, but
are quite expensive. The highest-output handheld unit is the
Lectrosonics UT400, at 100mW. But frankly, I think that with a clear
frequency, 100mW is more than enough transmission power.

Then, I'd suggest getting a directional antenna setup, which will
maximize the range you can acheive. I do agree with Scott, though,
that you should work to get the receiver as close to the transmitter
as possible. I don't think that you need to get it 50 ft away, though.
Modern equipment can give you more range than that!

I hope this gets you started in the right direction, but please feel
free to contact me to discuss your application further - 505-994-9859.

(Thanks, George)

What are you using it for and where? only on the 50' for half time,
or the end zones also? I would have the receiver on the sidelines with
a line level line back to the booth for control. I would get a multi
frequency diversity UHF unit. Then you can steer around any frequency
conflicts. Shure and telex make reasonable models. I would then get an
antenna manifold that has gain. Then put the two directional antennas on
stands up in the air. with the two diversity antennas remoted and on
longer cables, you could move them around to suit what your doing.
