Improving Indoor celphone and 800mhz reception ?

[FireGuy]

How can you get a better signal into a office building so that

when you use a celphone or 800mhz trunked portable in the

building their won't be as many dead spots.

Is there a leaky cable system,radiac or anyway to pick up the signals

passively to a outside antenna with a amplifier.

Someone asked me this today and i really didn't know if there

is a system that someone makes that can do that

so of course this is the place to ask.

Thanks

Basiclly, you throw money at it.

You need a directional antenna on the roof pointed at the site. That has to be connected to a very high quality bi-directional amplifier system. It needs to amplify the good stuff and filter out the bad stuff.

Then you need some kind of distrobution in the building. There is leaky coax called Radiax that works quite nice.

It is going to cost a lot of money to do it right.

Not at all true, depending on you proximity to a cedll site, or transmitter for other services, you can merely take a hi-gain yagi point it at it run some coax to the problem area and put a mobile antenna, on a good ground plane. We have used this in a number of basements, even on VHF and have had good results. Another way is if you need more signal, and can run 2 runs of coax, use 2 yagi's 2 mobile antenna'a and put RX amps going in the appropriate direction. This was,and is still used by NYPD to cover some of the underground subway stations for the local precient frequency.

Lot's of companies offer 800MHz enhancement systems. Spotwave comes to mind.
