4 x 6 element LFA 6m EME Array
The G0KSC 6 element LFA was chosen because of the very low side and rear lobes, especially when stacked.
This reduces the pickup of local noise sources to improve the receive performance.

An experimental four wide / low height configuration aimed at moon set for 6m EME.
mid-September 2022. This array is now dismantled ... but it will return as 2x2 on an "H" frame with az/el rotation to track the moon.
A 'work in progress' ... more to follow as it happens.
