I can't find the Vertical from DX Engineering. If you can send me a link it
will be great.
One solution might be top hat vertical, similar with
http://dl2kq.de/ant/3-1.htm . Not sure how much power is lost in the
matching unit L1, C1.
I would love a Waller Flag too. Imposible to buy one from here (too
expensive) but I might wanna try build one. Preamp will be the biggest
problem.
