Hi Jim, I suspect your BOG signal strengths and perhaps directivity might have benefited from using a matching transformer and perhaps a separate ground for the antenna from the receiver ground. There are a number of references available, for example: http://www.seed-solutions.com/gregordy/Amateur%20Radio/Experimentation/Beverage.htm (look at the "Basic Beverage Antenna" schematic as it shows the concept of using a separate ground; termination is optional) http://www.isp.ca/ve3nh/rxant.htm (although I wonder about the -61 material recommended here) http://n1eu.com/topband/BeverageXfmrs.htm and the detailed information on building them at http://www.dxing.info/equipment/ Commercial versions are available also, usually at premium prices. You didn't seem to have noise problems at that site, which a transformer and separate ground would be most useful in mitigating, but it would be interesting to see whether signal strengths and directivity also improve. best wishes, Nick ***************************** Nick Hall-Patch Victoria, BC Canada _______________________________________________ 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]
