Signal booster and splitter for 2nd 3G router

[magicfoot]

I have a 3G router installed in a basement and am using an external omni-directional antenna to get my 3G signal.

I now want to install a second 3G router in the basement about 5m away. Can I do this by simply splitting the feed cable in the basement and placing a signal booster before the split ? Where could I buy the booster, cable splitter and coax in Johannesburg ?

I have contacted a popular antenna company in Jhb to ask for a quote and they insist on doing a site inspection first. Then they want to create a report and do a second site visit to install the goods. Am I expecting too much when I ask them to install the signal booster and cable splitter during one site visit ?

Can anyone recommend any companies not starting with a P that do this sort of install. I have several sites that need this sort of work.

AFAIK, signal splitters work only with receiving-only devices like TV-sets. 3G router is also transmitting signal (two way communication). It will affect connection of other device unless there is sufficient gap between two bands. By example if you have Vodacom SIM on one router and MTN on the second, they both use the same frequency range. For this reason splitters are not generally available.
Why do you want second router at first place? Answering this question would help getting right answer.

The second 3G router is for a different end point device and is maintained under a different agreement. What you write regarding the two way transmission makes sense. Is it even possible to share the one antenna between the two 3G routers? I suspect not as there would be a conflict in transmission. Your comment ?

It would make sense to install a second external antenna to service the 2nd 3G router as a simple (and possibly only) solution. Is this correct ?

Yes. Just make sufficient spacing between two antennas, so interaction is minimal. If both antennas are directional and signal comes from different directions, you can install two antennas on the same pole (still maintaining vertical spacing).

Ok. Minimal coupling between the antennas if planted vertically I imagine (with adequate separation). I am going to ask the company starting with a P to do this work. Is there anyone else considering who do this sort of install on a national level ?

It is counting in wavelenghts as a unit. Ask any installer.
