Basically took section 4 in this one, and turned it into a comic book. Dandy little handout, if I can find the thing, I'll turn it into a PDF.

Not even close, it's a little comic book sort of booklet.

Sort of like this

Only not quite as elaborate.

The US publication you are looking for is called:

"What's Up?" Know how to repair and fabricate antennas.  TC 11-5. 29 April 1977

It was issued in the CF as B-GL-T11-005/FP-000

A small little 45 page pamphlet in five parts:

1) Antenna Types
2) Antenna Connections
3) Antenna First Aid (Field Expedients)
4) Formulas and Quick Reference Charts
5) Reccomendations and Reminders.

Great little pub.  I have had mine since I was given it in 1989. 

Cheers,

MC

Wow, 6 yrs ago make a statement on a site and re-read it again to find out that what I said came true!  Too bad I can't get PER points for that, lol.

Not exactly a field expedient antenna but, thanks to a US company, a better way to package SATCOM antennas for rapidly deployable units.

It is ill that men should kill one another in seditions, tumults and wars; but it is worse to bring nations to such misery, weakness and baseness
as to have neither strength nor courage to contend for anything; to have nothing left worth defending and to give the name of peace to desolation.
Algernon Sidney in Discourses Concerning Government, (1698)

I cut a few AE before I even joined the military, so it was a bit of a refresher, and we didn't cover it in in great detail on my 3s. We did however make up the basic dipole arrangement with insulators and a cobra head for the 138.

Long story short I believe we've gotten away from expedients because they were most effectively and commonly used with HF. Seeing as Satcom and such has really decreased the use of HF (which is a pity in my eyes) we naturally saw a decrease in expedient AE.

As long as you remember the formula -    Wavelength = Speed of light (300 for M, 926 for Ft) / Freq in Mhz then you're good to go.

The best one I ever made was for an old artillery warrant. I had an old CRT television in the back of my LS in Shilo and was playing games on it. He found out and demanded that 'as a jimmy I had to get him the leafs game.'   This was when CBC Winnipeg still broadcasted over the air.

I took WD wire, wrapped one strand around the outside of the coax on the tv, stuck the other into the center. Ran it up to the roof where I unscrewed one of my VHF AE and laid it on it's side. Connected it all, tuned to the channel and turned the Spud 1 on its side until it came in clear. He was very pleased haha.
