I guess I am unsure as to how the loop gets connected.
since the loop and cap are currently parallel, removing the cap
leaves me with 2 ends of the loop. Putting the cap in series with the
center of the coax feedline allows me to have only one connection to
the loop.
Did I miss something?
Someone else will probably have to transate the following for you (I must
have an upside down view of the world from down under):
Disconnect both wires from the capacitor.
sorry, I'm not trying to be an ass here but the diagram I have shows 3
connections to the cap. 2 for the loop and one for the center conductor of
the feedline.
Is my diagram whats confusing the issue?
Now cut the centre wire from the loop the the feed line coax in the tee
box... there is only one wire that fits this description.
Insert the tuning capacitor (two wires) where you cut the centre
conductor , ie connect the capacitor wires to each side of where you cut
the centre conductor
The capacitor is now in series with the centre conductor of the feedline
connection in the tuning / matching box.
Now connect a 100pF fixed capacitor between the feedline centre conductor
and shield in the tuning box.
Now adjust the capacitor for maximum rx noise.
