determines resonance and needs to be variable unless you were lucky and found
the correct value. The shunt portion of the coil affects the feed impedance.
This shunt portion is like the hairpin match for a yagi. You
There is a product called "Liquid Tape" that is available from hardware stores

A short length of SH 40 PVC pipe with end caps works good. Cement only

enclosed hardware.
