    It is short in comparison to the wavelength - but remember it sends DC up the coax and has active electronics directly at the feed point, and then back at the receiver input. The L-400B is even shorter (<1m) but I really haven't had a chance to experiment with that too much.

    I'm still tweaking the load coil / match for the best SWR, but here's what I was hearing last night on the WSPR 630m rig using the CCW.
