Looking to stack these 8 folded dipoles on my 100ft tower.

I can not find any information whatsoever on these. I have 4 consecutive serial numbered boxes.

Bluewave Marathon
138 - 174 MHz
Gain 5.5dBd

Looking for information on an appropriate phasing harness and spacing.

    $\begingroup$ What is the actual goal of this? And is it 8 individual folded dipoles, or 8 pairs like the photo? $\endgroup$

  • $\begingroup$ 4 boxes, 4 pairs, for a total of 8 individual folded dipoles. Can configure 4 TX and 4 RX or stack all 8 and use a Sinclair duplexer. $\endgroup$
