Here's a "drawing" of sorts for the T2FD

If you don't tilt it, it will look like this, sort of...

300 Ohm
Twin Lead
The spacing is 18 inches between the conductirs, and the length
is 47 feet. This is for 80 - 10 Meters. Seeing that the B&W version
is 90 feet long, and listed for 160 - 10 Meters, you could double the
length to add the 160 Meter band. I am putting the 47 foot version
up for my test here, using 1/2" CPVC pipe for the spreaders and
insulators, and putting the terminating resistor in a length of 1/2"
pipe for weatherproofing. One reply that I got, thru the local DX
Cluster, indicated that the losses, from 10 MHz up, should "only" be
3 dB, and based this on an article by Floyd, WA2WVL in QST last year
on a set of terminated long wires for broadband HF coverage.
I guess that we will see how lossy it is. I will be comparing it
with inverted vees on 80 - 10 meters.
