I'm trying to identify this antenna. A friend of mine rescued it from the dumpster where he works (there were six of them, and I got one). He's an electrical engineer and holds an Extra Class license, yet he didn't know right off what it was, other than a VHF-UHF multi-band (I suspect he left identification up to me as an exercise). He knows I'm into scanning and have the ability to put an antenna up high (35' over local terrain), and he thought it might be a good starter base-antenna for me. There are no numbers or identifying marks of any kind. The longest element measures 69.5", the second longest measures 48", and the short element measures 16.5". The three horizontal radials measure 77.5" each. (The center element and radials are adjustable; the lengths are how I found them.) I did the math on the elements for 1/4 wave and 1/2 wave, and nothing fell within any common bands. I then calculated 5/8 wave, and the two shorter elements landed mid-band for 70cm and 2m. The longest element came close to mid-band for FM broadcast at 5/8 wave. ???
The connector is a N-type with a BNC adapter. I connected my GRE PSR-500 with a 6', 50 ohm coax, at ground level, but did not notice any improvement in reception on any bands, and in some cases, worse than my Diamond RH77CA. Of course again, this was not up high, but at ground level, and inside.
The antenna was free, so if it doesn't work out for scanning, it's no big deal. I'm just wondering if it's worth mounting up high.
