Title: simple question about antenna
Post by si9dan2011 on May 15^th, 2017, 1:38am

Hi all, I would like to know, if a good performance Tx antenna is also a good Rx antenna. Assumed all Tx and Rx conditions are same.

Thanks.

Thank you for your reply Cheap.
So let say, if I tuned my transceiver antenna to which I found the field strength during the transmission is maximum, can I assume I will receive a good signal also?

Do you have very basic knowledge about linear circuit ?
