Just measured the 'hairpin' coil for my 160m 38 foot top loaded - coil
and 2 x 18 foot wires - antenna.
Feedpoint impedance without match is 12 ohms.
Placing shunt coil to ground of 1.7microH and tx sees 50 ohm 1:1.
Only problem with the vertical being so short the bandwidth is only 12
khz between 2:1 points.

The excellent web site for calculating matching network values should have been:
http://home.sandiego.edu/~ekim/e194rfs01/jwmatcher/matcher2.html
not the one I posted yesterday.
