Thanks for the schematic! This simplicity opens up a lot of options. Got the Mag Mount thread already open, but didn´t get around to it.
Possibly stupid q: If I don´t use the base I´d use a ground plane or where do I hook the shield?
I think I remember some VERBALLY grounded radio with a flat antenna (300 Ohms?) cable from my youth (for AM radio?). <grin>
Nothing else than the mains ground??
You´re also confusing me with your Quick Spider article. The RG6 apparently is 75 Ohms and not 50, like the RG174.
And is there a reason that the stuck-in radial part is 21 mm?
Lotsa q!
