I am a firm believer in HF dipoles as the simplest, cheapest and most effective field antennas. I don't try to get them up high, since I usually work 80m NVIS when I'm "cabin camping". (Besides, I throw like a girl). I do use a gin pole made of MS-116 and MS-117 mast sections with a pulley on the end to hoist a wire into a tree. I like to make reel-out dipoles. My first one was made from two hand-crank antenna wire reels from the famous AN/CRT-3 "Gibson Girl" liferaft transmitter. Later versions used the more readily-available camper's clotheslines and carpenter's chalk line reels. For heavier dipoles, I did find an online source of genuine MIL-spec reels. Just add your choice of wire. (The same source also carries new, preserved 1967 vintage magnetic headphones, much better for CW than the modern hi-fi 'phones). 73, Bob WB2VUF Tim,

Great antenna kit! I am a firm believer in HF dipoles as the simplest, cheapest and most effective field antennas. I don’t try to get them up high, since I usually work 80m NVIS when I’m “cabin camping”. (Besides, I throw like a girl).

I should try and get something like this going in the Rochester NY area. These radios are just great when deployed in the field. Rw These are wonderful pictures.

The Alphas and most (all?) Betas would be blocked by the glass envelope if it's not broken. The Gammas would get through. I tested an old OB2 voltage regulator tube which may contain an isotope to partially ionize the gas in the tube. Just observed background counts.

Out of curiosity, have you ever examined Thoriated-Tungsten tube filaments with your Geiger counter? I'd be curious to know what levels they emit. DE N6MKC Very interesting, Tim.
