Powell, Craig Healy just wrote a fair amount on the subject. First of all, the beverage is horizontally polarized; the WABV tower vertically polarized. That means the coupling between the two would be minimal. In the event that the beverage DOES modify the ND pattern of WABV, it would be a matter of detuning the beverage so that it becomes "invisible" at 1590 kHz. Craig wrote a piece a while ago about using a beverage strung next to a radiating tower. It would probably be necessary to put a trap in the beverage/receiver feedline to prevent overloading the receiver while the station is on the air. Otherwise, no great problem. That is, unless the beverage is next to a high-power station. I don't remember Craig commenting on problems with a beverage distorting the DA pattern of a station. 73, Charles Charles A Taylor, WD4INP Greenville, North Carolina _______________________________________________ IRCA mailing list [email protected] http://montreal.kotalampi.com/mailman/listinfo/irca Opinions expressed in messages on this mailing list are those of the original contributors and do not necessarily reflect the opinion of the IRCA, its editors, publishing staff, or officers For more information: http://www.ircaonline.org To Post a message: [email protected]
