Improving FM in building
 

The health club I belong to has poor FM reception inside the building.
I'm trying to get them to improve it. The thought I have is to install
an outside omni antenna and connect it to an inside identical antenna
hanging down from the ceiling.
Is this a workable idea?
Does anyone have info to help make the improvements?

Thanks
Mike
PS---This is for all the personal FM radios worn by the exercisers.

Hi Mike,

Your idea is a necessary step in any solution. As it is the cheapest,
try it first and you may need to go no further. It has a high
likelihood of achieving what you want.

Good point. Might as well start simple.

If they have cable TV in the club you can put a set of rabbit ears
in one of the outlets and see if that helps. A preamp may help too.

Irv,
Have you any idea about the lengths which cable TV operators go to to
keep their networks RF-tight (ingress and egress)? Feed an outlet into
antenna? Maybe not such a good idea!!

Yeah, that's likely to cause problems. The rabbit ears will "leak"
signals that the cable company has no right to be broadcasting... some
of the cable channels overlap with air-traffic control frequencies,
amateur radio, and so forth.

Complaints are likely to arise, either because the egress leakage from
the cable through the rabbit ears interferes with licensed radio
services, or because a licensed transmitter somewhere in the area of
the club leaks back into the cable and wipes out TV reception for
other cable customers.

Upon locating the source of the problem, the cable company *might* be
polite enough to simply insist on disconnecting and terminating the
cable outlet in question. Or (depending on how irritated their Cable
Guy is that day) they might just cut off the cable service to the club
entirely.

It might work OK, especially if the building is really sealed tight to
RF.

You may want to add a cheap FM preamp with the outside antenna
connected to the input and the inside antenna connected to the output,
so that the connection between the antennas has a tad of gain, rather
than just loss.

This works for GPS. I had a project at China Lake Naval Weapons Center a
few yeards ago, where they pumped GPS through an amp and rebroadcast it in
the lab where they were evaluating a missile guidance syatem.

(It doesn't matter how sure I was that there was no fuel and no warhead in
the missile; I did NOT like walking in front of that thing.)

Ian-

In that case, why not get the Cable TV people to install it for you? They
can use an isolation amplifier that will prevent outside signals from
being fed back into their system.
