hi,

i happen to break the antenna of my TX with the connecting wire also

Then i reconnected the antenna back but there is a major reduction in range less than 100 meters without the satellite receiver.

Do you know any way the basic range of the TX can be increased

bump

Did you reduced or increased the original length of connecting wire? Please explain How you fixed it back on Tx.

yes, as the wire got short due to breakage i put a one inch normal wire to connect the antenna.

That is what went wrong.
Remove that 1" normal wire. And solder the original wire as it was. then check and post here the result.
