'Hello Justin,

new 4x8 LFA array is up and running!

Today I made the first EME QSO and I must admit that performances are astonishing! I got a lot of very loud echoes when Moon was elevated above horizon then, when the Moon was around 5° of elevation, I started to hear very huge echoes with strongest around -7db measured with WSJT and Spectran. Ground gain is a good boost!

I kept to get strong echoes even when Moon was already below the horizon so, when the natural satellite was around -1°, I started to call K2ZD who was calling CQ. We completed easily and I received RRR from Mario with my Moon at -2.6° below horizon! I couldn’t believe that! The antenna temperature is really very low and I measured it about 4db better than my previous 4x7 array. The F/B also is superb, around 30db with very clean pattern and low side lobes.

I enclose to this email some pictures of the array.

I’ll keep you informed about the tests I’ll run during next days.

Very ’73 de

'Hi Justin
I built a 5 ele LFA on a 4.1m boom last week and finished it this morning. Followed your instructions and everything worked out spot on. Put it up on a 6.5m length of pipe to check everything was ok before mounting it on top of the tower and within 1 hour had worked 6 JA all on ssb.


Thanks for sharing your knowledge and antenna design.
