Maybe so, but Jim Weir has been advocating this design for probably 30
years, lots of th
Any dipole antenna design that requires ferrite toroids is wasting
transmitter power due to the mismatch between the rf cable and the antenna
elements. The usual situation is the cable has a characteristic impedance
of 50 ohms; the antenna should have an impedance of 50 ohms for optimum rf

I ordered my first antenna kit from RST way back when I was building
N56ML, and that antenna worked fabulously. When I bought N891JF over
two years ago, it had serious antenna issues, and I thought I'd need to
build another one, so I ordered another kit from RST, but then corrected
the issue a
I ordered the RST antenna kit from RST about 6 weeks ago and haven't heard
boo from them. I am rapidly approaching 45 days from the order date and
will have to file a claim with Paypal before that deadline on the chance
that it was sent but lost.
Question
Should RST decide to cancel my order rat
That would be the kit that is built into the leading edge of my vertical stab.
During one flight home from the Gathering in Mt Vernon, I was over mid Oklahoma

If you type 1/2 " copper tape in Google, you find heaps, but most is
adhesive back, IS that OK Mark?

Mark,
I had used your suggestion as far as running the tube down into the back of the
boat below the vertical stabilizer but used a PVC water faucet supply tube from
one of the box stores. I just cut the length I needed to wrap the copper tape
around and epoxied it in place. Worked great and

It comes in 3' lengths, as I recall. Let me know when you find a source...I
need to order some more! Thin wall aluminum tubing would work OK as
well...maybe less trouble too.

I "rolled" it around a small diameter dowel to get it started, and then
slid it down the shaft longways (see enclosed photo), before soldering
to the coax. Arrow shaft is

Thanks Mark. I knew what I was trying to say but something got lost between my
brain and the keyboard. I wasn't sure if you knew some secret to the dipole
configuration. My father was a Ham operator and designed antennas. He would
often come up with unique and strange setups. I should have paid

After rereading your question, I think I answered the wrong question...or
you may asked the wrong question...or both. Although the shield can be used
as one of the legs, I chose to use the copper tape, which has more surface
