[TowerTalk] 1/8 wave spaced 80m verticals

[Col]

Can anyone help me with the construction of a lewallen phasing network for 2
1/8 wave spaced 80m verticals or sort out my christman feed. I have used 2 x
mfj1792 top loaded verticals. I have 40 radials 1/8 wave long on each
antenna. I have tried the christman feed to these antennas but i suspect the
phasing is not quite right as front to back is only about 15db. I used the
design in on4un low band dxing, 29 degrees and 157 degrees. I have
subsequently learned that this will be specific line lengths for full
size1/4 wave verticals.

I have limited test gear available so I thought the christman feed would be
the simplest to construct. I would like to improve the front to back on the
array, any thoughts

many thanks Colin GM0RLZ
