I have an MFJ 9040 and want to make it totally portable. No tuner, etc. I

Won't I need to use some feedline? If so, how do I connect it to 20-22gg
wire? I need to make this as cheaply as possible. Interested in just
throwing the antenna up or down a balcony etc.


Hi Greg,

Both your description above AND the manual scream "use a tuner."

A "tuned" antenna is only tuned to its environment, and unless you
take that environment with you on the road, that antenna is NOT going
to be tuned. However, there is much to be said for sloppy
installations being so lossy as to match every time. A low dipole
often so qualifies. However, a longwire cut to frequency (something
of a contradiction in terms, by the way) would then depend on the
ground path attached to your MFJ. If you are thinking of cut to
frequency in the sense of a halfwave, then you are driving a severe
mismatch (which that manual also screams may lead to spurs).

Get the drift?
