Topband: end-fire array

[donovanf at erols.com]

Hi Andy, 


Your new end-fire array sounds excellent! 


How are your two elements constructed? 


What is the end-fire phase delay between your two elements? 


Are the end fire elements actually 125 meters apart? 
1/4 wavelength end-fire spacing would be 41 meters. 
Spacings as small as 20 meters work well in an end-fire array 
(the RDF is slightly better) but signal level is somewhat lower 
but much better than a BOG. 


Good luck with your new antenna!

Saturday I built my new end-fire array to NA.Today I compared my 68m long BOG, the 353m beverageand the 2x125m end-fire array , all antennas beaming 300° NA.I am listening to W1AW beacon for this comparison.
