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
page, please do.
Below are all of the forum threads, including all
the responses to the original posts.
Post subject: Will this Work?

I'm brand new to the forums.
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
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?
have any idea of the transmitters power or the receivers
The manufactors states about
100 M line of site operation if that helps.
