Bruce N3XUK Hi Bruce , Gotham antennas were popular in the 1960 maybe into the early 70's.. They went out of business so your not likely to find any info on them.. But basically the vertical you have was the same as the Hy- gain 18 V.. which uses a base loading coil to present a half decent match to 50 ohm line. I've long since lost the coil I had with the Gotham vertical I used as a novice .. I would guess you would want a coil of about 2.5 inches Dia. and about 40 turns.. A btter way to put that antenna on 80m would be to top load it somehow. In any event you'll need a good ground radial system. 73 Dave kc1di |

![]() Keyboard or Bruce, The 'infamous' Gotham vertical was base loaded with a coil about the size a typical 'BugCatcher's, something in the 50 - 90 uH range. The usual advertisement showed a grounding stake used for a ground, maybe the water pipes. The Gotham company started in New Jersey, later moved to Florida where it branched out into other things, then folded. It was a fairly 'cheap' antenna for the time. If you plan to use one don't expect any more performance than you would get with a 'BugCatcher', which isn't much on 80 meters when compared to many other antennas (non-mobile), but certainly better than 'nuth'n'. Also expect to have to use more than a single ground rod or the water lines for a ground. I wouldn't go so far as to say it was junk, but it sure came close... Good luck! 'Doc |

I once had a Gotham which worked very well. Somewhere I have a sales
brochure, I will dig it out and mail you a copy if you will contact me direct and give me a mailing address to send it to Just might have some other info., I will send you copies of what I have. It's good antenna that serves it purpose, great to start with. Jim, kf4tun "Keyboard In The Wilderness" wrote in message news:k82zb.641$yf.196@fed1read01...
