The antenna cover i designed last year was a little bit long (https://www.thingiverse.com/thing:2999573). It always gets in the way when packing the transmitter. So i designed this shorter version.
To get it more compact, it is in two parts which screw into each other.
To assemble it, first take the inner part, insert it into the hole, then feed the cable of the SMA Connector trough. After that you can put the sma connector trough the cap part and screw the nut on. Carefully screw on the cap now, try not to twist the connector wire too much.
To secure everything in place just screw the metal plate from the original part back in the bottom.
