The Fine Things are Always Hand Made
I have a Super Antenna Coupler. Anyone know how to build the super antenna that connects with this coupler? See picture.

It is a double dipole wire antenna with twin lead in to your outboard antenna coupler/switch (early version aprox 1934-36).
Your coupler is usually seen screwed to the tube shield of the IF amp tube located in the middle of the back of the radio. You may find one of your tube shields is already drilled for that screw. This version Scott antenna is appropriate for the AW-15 and AW-23 models which have the single antenna post. Use the Broadcast position for the broadcast band and low end of the next band. And the Short wave position for the rest of the shortwave bands. (If you have this switch in the wrong position, you get little or no reception).
Kent may have the 4 page Scott instructions as a PDF. If not, I can make an image of mine. I built my own reproduction many years ago using the information and dimensions from this publication. I also used it on my Philharmonic without using the coupler unit.
There is a later version Scott Super antenna developed for the late 1930's Scotts having 2 antenna posts. This version has a transformer that hangs at the junction of the wires that form the double dipole antenna.

I also have a copy of the antenna info scanned. It does require about 50 feet of space to install. I also have the coupler on my set, but am using the radio with a 53 foot long wire draped around our dining room. I do have an antenna ready to go on the roof, as soon as it is safe to do. It is also a long wire with a balun and coax feed to the radio.
If no one else offers, I can send you the plans.

Thom,
If you have it handy I would appreciate your sending it.
How do I get you my email address?
Thanks,
Joe
Here is an image of an Scott Super Antenna - mid 1930's version used with the 2 position coupler switch.
From my file of various pictures down loaded from ebay ... the rear of an AW-23 shows the recommended position for the coupler switch - on the middle tube shield.
Her is part of the Scott infor for the Super Antenna - shows dimensions and layout. It is a little unclear but top lengths are 29, not 24 ft
Thanks for the info, David.
Rather complicated isn't it....
My coupler is connected identical to the pictures.
Thanks again,
Joe
One more thing, the twisted wire transmission line from the junction of the double dipole wires to the radio needs to be exactly 110 ft with any excess coiled in the radio cabinet. If 110 ft is not long enough, double it to 220 ft.
Look closely at the diagram. The antenna is made from 2 multi strand wires, each is 29 + 16.5 = 45.5 ft long. The top left goes to the bottom right, and one lead in wire connects at the junction. The other wire is the mirror image and connected to the other lead in wire. The two halves are kept separate at the insulator where they come together. The wire is multi strand. The Radio Shack 50 foot long wire antenna kits I used for mine seem to be no longer available.
As for a lightning arrestor, Scott recommended the Vis-O-Glo which has two small neon bulbs inside to discharge static electricity from the antenna. I have sees both clear glass and clear plastic construction for the body of the Vis-O-Glo.

If you aren't already aware, there is a copy of the antenna instructions on e-bay. This is a later version of the instructions I have, in that it has a matching system at the antenna end. The early version I have doesn't.
Let us know how everything works out.
