[Hi-zreceivingarraydiscussions] Detuning antennas when using 4 square

Gentlemen and Yls, 

       I am using a Hi-Z four square and find that then my 160M inverted L
is down that it works better on both TB and 80M.   Obviously there is an
interaction and yes it is certainly closer than two hundred feet to the
closest point of the 4 sq.    What method of detuning antennas such as the
inverted L is normally used?    I suppose a relay switching in or out is
part of the system and the problem then becomes that when operating on TB
the TX antenna must be detuned possibly slowing down operations and if not
properly thought out problematic for a power amplifier.

 

       I am most pleased that Hi-Z is again actively trading.    The product
is good and the service of equal value.   Long may this company be with us.

 

                                     73 Doug EI2CN
