Title: T connector for using 2 antennas...
Post by: Devanesan Andrews on January 29, 2017, 12:43:04 PM
Hi folks...  Got some confusion

I would like to increase the reliability of the radio system....

Wanna know whether I can use a t Sma connector to my rctx as well as my video Tx to increase their reliability... Specially to the 433mhz telemetry of ardupilot...

I figured out when the plane take a circle or a bank there are loss in the packets...  Can I use the t connector ant two antennas to make it proper... I read somewhere in RCG that it can burn RF... experts pls guide me...

Regards
Devanesanandrews

Very interesting solution , I remember I also asked this question to someone they suggested me not to attempt such things. The most probably reasons that come to my mind is that antenna mismatching of attaneuation and impedance . Or something like that .
Instead using a rfm900 modem will be a safer bet.

Bro I am planning to use same antenna which is identical every way...

I am planning to use rubber duck... With same decibel..
I am not planning to use patch and cloverleaf...

not ideal - you will change the wave length of each antenna ... as you are effectively
doubling the active length ...( the unshielded part..)


may be some rf expert can chip in..
