6 el. Yagi DJ9BV for 6 meters (by EA4BAS)
This antenna was manufactured by Miguel, EA4BAS
for his operation as EH4BAS/5 from IM98TL in August 2000
Design details
Gain: 11,61 dBi
F/B: 15,61 dB
(using the program QUICK YAGUI v. 4.0 by WA7RAI)



Modification to the antenna based on
the BV6 by DJ9BV
(Changing the boom to 7,32 meters, the length
of the elements and the spacing)
With the same program the gain now is 12,43
dBi and the Front to Back (F/B) 35,19 dB
So, it's worth the hassle.........
The antenna on the air at IM98TL !!
