Phased verticals for 30m
With the 3Y0J dxpedition on air, and 30m being used alot, I did what I could to get a qso.
I have an inverted vee, fed with ladderline and a link tuner, which tunes on 30, but I wanted to try something a bit more directive.
Settled for 2 phased verticals which turned out nice.
Had 2 identical 6m fishing rods, which were extended using military surplus tent poles (Nato stuff). Had made a bunch of the ground plates at my last job, so it was a quick job throwing the antennas together. Used 2 elevated radial per vertical and used christmann phasing. The nano vna was very useful when cutting the feed and delay lines.
Here´s a link to the VA7ST pahsing line calculator.

Tests with a nearby station showed approx 10db stronger signal than compared to the vee. RBN spots showed around 6db in favour of the phased verticals over the vee. This antenna might be a keeper.
So, what about 3Y0J. No qso yet, but my hopes are still up.
