This looks like maybe some sort of copy of the Hy-Gain Penetrator 500, the first CB Antenna to be advertised to take 1500 watts back in the day as many Ham Linear Amplifiers could put out 1500 watts if kicked hard enough. See: Hy-gain Model 500 "Penetrator 500" (cbtricks.com) Jay in the Great...

Gee Whiz what is the difference between the PDL-1 and PDL-11 ?? Jay in the Great Mojave Desert

Hello All: Yeah the plastic hubs will probably need to be replaced with Teflon, Dilrin, or even Fiberglass. Oh and the Cast Aluminum metal Hub is know for having internal cracks and falling apart right out of the box being brand new. But other than that it looks original to me, and rebuildable...

Hello Moleculo: I have both a 117 and a 77 and they simply work great. The only thing that I have done is to make a set of test leads with mix 31 chokes and a 1000pF cap bypassing the leads to keep RF out of the meter. Is work good G.I. Jay in the Great Mojave Desert

Wow that happens in ice, what make of antenna is that? Jay in the Great Mojave Desert

Hello All: I have heard of the Big Mac Antenna, it would be very interesting to see the assembly instructions and manual. Probably could duplicated using heaver Aluminum Tubing and even light Nylon (Parachute) guy wires to support its long length. Jay in the Great Mojave Desert

Hello HomerBB: Great posting of hands on radio stuff with different antennas. Thanks. The local hams here in the desert wanted to start up a local 20 meter yep yap frequency. I had a simple 20M dipole antenna with a 1 to 1 current Balun and old RG8X coax I had for years. On a 45 degree angle...

Yo Ranch55: Great photos shows all, and good fix. I have never liked nuts directly up against ceramic insulators without a flat washer to smooth the pressure against the ceramic insulator and not have a twisted force against it. Jay in the Great Mojave Desert.... "Next Gas 150 Miles"

Hello Cakeman: Yeah the top of the roof or apex is a great place to put the antenna mast. I install another 2x6 board on the inside and outside of the apex to reinforce just to make me feel better. This allows the mast to be mounted to the outside 2x6 board keeping the mast away from the...

During out local Jeep Club runs in the Desert I get a lot questions on the radios and such, as some of those guys are preppers I think. They want to know about Ham Radio and the repeater systems. So I give them a little radio check demo on the local repeater, we got a few repeaters with great...

Will have to check the local CB to VHF Repeater. Was up humming and ah buzzin a few weeks ago. Not bad audio either or coverage. I still think most CB traffic is simplex, right. Jay in the Great Mojave Desert

Yeah that's kind of a confusing thing there how they call tubing or pipe. When I order Aluminum Tubbing or Aluminum Pipe the vendors catalog calls out Outside diameter with a wall thickness spec, for both. But has the tubing and pipe on separate sections. Had to replace some galvanized water...

I said the wrong thing in posting #18. I said I installed "Aluminum Tubing" at top of the tower to get another 10 feet of antenna height. Tubing is way thinner than Aluminum Pipe. So I should have said "Aluminum Pipe, The Aluminum Pipe is made of 6061T6, its 12 feet long, with a wall thickness...

One of the neat-o keen-o things Ive done is to install a Aluminum Tubing on top of the tower to give the antenna another 10 feet of height. Had it up for years taking all the Santa Ana Wind Storms and desert winds. Its 1/4 wall thickness 6061T6 12 feet long and its bullet proof. Yep it has Guy...

Hello Gary and All: I was able to talk to the guys running the MC12 radios a small shop on Burbank Blvd, in Burbank, not to far from the old General Radiotelephone shop. They said the same thing about the FCC, which nobody cared if it was FCC approved or not, it was a very loud radio as you...

Vert and Horz, must be new design. Yeah Mustang, I was on top of the Ridge in Palmdale in my 4X4 truck avoiding all the AH's from southern ca going way to fast. I turned around not because of the snow, but knowing more snow and more ya hoos will be on the road. Jay in the Great Mojave desert

Wow 131 just were is that at with all the snow? The crank up/down towers are well worth the extra money and time, I have quit a few. My main tower is on a trailor and it cranks up/down, and tilts over so that uninformed antenna adjustments can be made easily. Its about 55 feet tall, and went...

Replying to a e-mail that bounced: Yes the radio is basically a modified General Radiotelephone Super MC11A that was real popular. The MC12 had two 6BQ5 tubes as the Modulator, were the MC11A used a German tube ECLL400 rare but expensive tube. Here is a photo of the MC11A Jay

Good advice from experience no dought. Got a chance to buy a used Ameritron Amp using the 3CX1500 tube. Local pick up only. Ok 2 Hrs plus drive into the big city of LA. Armed with my own Watt Meter and Dummy Load and Jumper Coax, I go. A disappointing way low output measurement with a 100 watts...
