I recently purchased Oregon Sensors, but as I live in a building lined with aluminum, and if i have the blinds drawn I do not receive the signal of the outdoor sensors …
I’m thinking of putting a second antenna to RFXtrx using a “T” connector, Does anyone know is feasible to put 2 antennas with a T connector and whether they would work both antennas with the same RFXtrx?
Antennas need to be matched to the coaxial transmission line and the coax in turn, to the transmitter/receiver electronics. It’s not a simple case of twisting a few bits of wire together. Having said that and given the application is not overly critical, you may be able to use an RG6 TV splitter like so:
You would just use it in reverse. The two aerials are connected to the two outputs using proper RG6 cable with F connectors and the input would connect to the electronics, again using the appropriate coax cabling. Not an ideal solution but may do the job, so worth trying.
