To: <topband@contesting.com> Rob, It really depends on which kind of loop you are talking about. If you mean the tuned loops shown in the handbook and the antenna books, then the impedance is quite h

To: <topband@contesting.com> Snip... The only parameter greatly affected by the terminating resistor value is directivity. If the value is correct, the response from the back will be minimized. The

To: <topband@contesting.com> Bill, A lot depends on what you call F/B ratio. Most of the modeling programs simply take the ratio of the pattern max and the pattern directly (exactly 180 degrees) behi

To: <topband@contesting.com> RF wise, it will work OK as long as the feedline follows the tower members to the ground. Effeciency and lightning protection are both enhanced with the proper bonding a

To: <topband@contesting.com> Tom, I think you meant to say "in spite of _load_ impedance excursions" here. The directional couplers are calibrated for a specific value of _line_ impedance. I realize
