[TenTec] 6 Meter Antenna

[Stuart Rohre]

You could adapt the loop for use on 6m, by use of a dedicated 6m tuner. 
Your present HF tuner likely has higher minimum inductance and capacitance 
than you will need for 6m.

An El net tuner could be fashioned that would be adequate for 6m work, as 
long as you float the return side of the circuit.  Or, if you want perfect 
balance, make a double El or even a double Pi circuit for 6m.

The stub length might need to be changed to a different length of coax for 
an optimum match.

A simple two or three element beam gives you the advantage on six meters of 
directing your signal into the propagation which usually favors only certain 
directions, thus the ability to rotate and concentrate your signal is 
valuable.  Aluminum tubing or construction aluminum from Home Depot could be 
made into beam elements and boom.  Or for lower power, you could convert 
larger TV antennas.

Check out the Handbooks of ARRL from the 1957 period for some 6m tuners 
schematics to give you an idea of range of capacitance needed and the 
inductors.   Remember, you want to match a range of impedances which you 
will have to determine either by use of an antenna analyzer or antenna 
modeling, if reusing your present loop.
