Will this Work? - RF Cafe Forums

Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the responses to the original posts.

Hi,

I'm brand new to the forums.

I recently bought a small meter reader which transmits temperature and meter info on 433 Mhz. The meter reader is located in a utility room; and I would like to put the receiver in another room.

Between the rooms, is concrete block. Ie nothing propagates out of the ulitity room. I think (I can't really tell) there is about 4 m between the rooms and walls. The walls are 15 cm thick; pour concrete block.

There is a 1 inch conduit between the rooms; I was thinking about sticking some coax in there, and put on some 400 Mhz or so antennas on each end, building sort of a passive relay system.
Would that work?

At the moment there is telephone wire in the conduit.. is there any way I could use that as an antenna?

I don't have any idea of the transmitters power or the receivers sensitivity.

The manufactors states about 100 M line of site operation if that helps.


Many thanks,
Sean
