Used 80-6 HF Antenna - What Do I Have?
Greetings to all the resident knowledge in this group.
I am trying to figure out what HF antenna I have. I bought it at an estate sale. It was mounted in the ground, without radials, but connected to a ground rod in the ground alongside the antenna. It was "at the beach", so while it is in overall pretty good shape there is some corrosion in places, and the UV has gotten to a couple of other places. I have gotten it on the air, and it covers 80-6 meters. I am hoping to be able to get a manual and perhaps some replacement parts. It is SIMILAR to an R7, but it is not an R7. The key points are that it does not have the base or middle radials, the matching network is different, the mounting is different and this covers 80-6 meters. It does have the stubs like an R7, however. I have searched CushCraft, Hustler, HyGain and Gap, and it does not appear to be a product made by any of them, based on online manuals of past and present models. Here goes the description, and I hope someone can point me in the right direction. BASE The base of the antenna is a 10 inch sleeve, 2 inch OD. The antenna mounts by slipping over a mounting pole, not alongside with U-bolts as is the case with just about everything else. MATCHING NETWORK The matching network, if that's what it is, is a "tuna can", about 1-1/2 inches in diameter and 1-1/2 inches high. There is an SO-239 on the bottom, which has some corrosion and the coax center conductor is not making good contact. There are little L-shaped tabs on the top and bottom, the bottom one going to the skirt/sleeve, and the top to the start of the radiating element. SECTION 1 This section is 85 inches long, topped with a 1 inch coil the same diameter as the aluminum tubing. Near the top is an L-shaped stub. Near the top of the stub is a support which is clamped to the next aluminum section. SECTION 2 This section is 4 inches long, topped with a 3/4 inch coil the same diameter as the aluminum tubing. Near the top is an L-shaped stub. Near the top of the stub is a support which is clamped to the next aluminum section. SECTION 3 This section is 6 inches long, topped with a 3-1/2 inch coil the same diameter as the aluminum tubing. Near the top is an L-shaped stub. Near the top of the stub is a support which is clamped to the next aluminum section. SECTION 4 This section is 3-1/4 inches long, topped with a 2 inch coil the same diameter as the aluminum tubing. Near the top is an L-shaped stub. Near the top of the stub is a support which is clamped to the next aluminum section. SECTION 5 This section is 12 inches long, topped with a 3 inch coil the same diameter as the aluminum tubing. Near the top is a U-shaped stub. Near the top of the stub is a support which is clamped to the next aluminum section. SECTION 6 This section is 24 inches long, topped with a 2-1/4 inch coil the same diameter as the aluminum tubing. Near the top is an L-shaped stub. Near the top of the stub is a support which is clamped to the next aluminum section. SECTION 7 This section is 36 inches long, topped with a 6 inch coil the same diameter as the aluminum tubing. Near the top is an inverted U-shaped stub. Near the top of the stub is a support which is clamped to the next aluminum section. SECTION 8 This section is 76 inches long. Approximately 6 inches from the bottom are two 24 inch horizontal elements, looking like 12 inch radials. I suspect these are some form of capacity hat. That's about it. Any help anyone can provide would really be appreciated. 73, Rick, WM6M |

[SNIP} 73, Rick, WM6M Rick - It sounds like you are describing"open coils" (and not enclosed traps) Sounds like the Bencher HF9VX which is 80 through 6 meters and stands about 26 feet tall. It does not require radials IF the CPK Capacitive Counterpoise Kit is used. http://www.bencher.com/hf9vx.html Manual for 1997 to Present model: http://www.bencher.com/pdfs/00408IZV.pdf Manual for earlier model 1989 to 1997 (used HF-6 as base) http://www.bencher.com/pdfs/00233IZV.pdf Bencher any replacement parts you may need (about 5 miles north of my QTH). w9gb |

I immediately thought of the AV-5 (but it can't run on 6 meters - that I am aware of) Cushcraft have made many vertical antennas (both 1/2 wave and 1/4 wave); R3, R4, R5, R6, R6000, R7, R7000, R8 (1/2 waves) AP8(A), AV-3, AV-4, AV-5 ========================== R5 1/2 wave maintenance and repair http://home.planet.nl/~fhvgeerligs/Ant/R5/onhr5eng.htm AP8 (PowerWave) http://mega.ist.utl.pt/~cmao/ham_radio/ham-04.html AV-x series (the AV-4 and AV-5 had a "X" capacity hat) I owned the AV-3 in the 1980s - nice 1/4 wave antenna - does need radials http://www.cushcraft.com/support/pdf/av3482.pdf w9gb |

Thanks, I think we are close! Mine is 9 bands, and easily tunes 6
meters, but otherwise it looks like the AP-8(A). Thanks for your help here. 73, Rick On Wed, 11 May 2005 19:38:37 -0500, "gb" wrote: "Little O'Me" wrote in message ardnews.com...

It sounds like you are describing "trombone capacitors" - BUT a photo would "say a thousand words" of description. Greg w9gb |

Thanks for your help here. 73, Rick I don't remember a 9 band version of the AP8(A). There were AP8 and AP8A versions. Cushcraft manual for AP8A (1/4 wave - needs radials): http://www.cushcraft.com/support/pdf/951435.pdf Cushcraft has since discontinued this model. There are web pages on how to clean/repair the "trombone traps" Greg w9gb |
