On feeding 1/2 wave vertical's which I have done on 40 meters (65 foot for 40 meters) by insulating the tower from the ground and matching with a coil to ground and tapping at a low impedance point (
The telephone companies used unbalanced double shielded 110 ohm coax for video (television). Nice stuff. I can't find a number on the coax. Its about the size of RG 8 with two insulated wires inside
Interesting stories on the trap verticals, vacuum relays etc. in the top of your vertical. Sounds like an engineers nightmare congratulations to anyone who can make them work and keep them working. I
I think we should listen to W1BB on the subject of inverted L 3/8 and also the inverted L 1/2 wave is also a excellent ant. Why does the computer say the 1/4 L has a lower angle, maybe because the co
It was great seeing the comments from the early topbanders on JA QSOs I found a note in my log about a early Japan to Iowa QSO that I listened to by the late W0NWX, W0DX, VP2VL, Bob Dennison of Newto
I bet many of you old time top band operators, like Herb, Tom, Barry and others remember the problems we use to have trying to keep the DX window clear of the phone stations. One station in the Midwe
Yes, I remember putting up a haywire grounded inverted U ant. across a creek in my back yard crossing about 30 foot of water, Guess the verticals were about 50 foot and horz close to 60 foot. Much to
Most of this week the aurora has made some beautiful night time viewing for us in the Northern and midwest states but its has caused strange conditions on the short wave bands. Barry W9UCW reports a
Years ago at my old QTH I used a large (capactance) variable capactor to match my 99 foot shunt fed vertical. This made it very easy to match and I never had problems with arcing. But I was using a T
I am not sure but I think WHO on 1040 kh in DesMoines, Iowa still uses a Franklin Antenna. The top 1/2 wave is isolated from the bottom 1/2 wave and is fed through a phase shift tuned ckt on the towe
I am not into 4 square vertical beams because of space problems but I have seen various methods of insulating verticals, many unreliable and expensive. But several years ago I shunt fed my one and on
I wonder if I should elevate the vertical of about 30 inches or if this snow will not affect the vertical... Anybody experienced this fact before.. I mean snow at the base of the vertical.... I have
Hello Gang, Lots of interesting talk on powering remote relays such as vacuum relays. I have been powering several remote relays at my 40/80/160 vertical for over ten years. Yes the Jennings RF1E rel
Hello Gang, I noticed someone commented that they thought 19 gauge wire was two small for radials. Gosh I hope not as I have a yard full of surplus telephone cloth covered inside telephone frame wire
This really hurts, losing Earl one of the top band greats. He was always experimenting with new ideas. I still have one of those 3 foot diameter loops in use that Earl pioneered in the 1970's. Still
I was having a awful time trying to work on my 160 vertical using a MFJ 259 analyzer due to Broadcast interference from a local BC station. I had to wait till the station went to night time low power
Years ago I used my 160 meter 3/8 wave inverted L on 80 meters with very good results. For 80 meters I used a L/C (coil-variable capacitor) at the base of the vertical leg which was in the basement n
another option that I used here for my radials was wooden doll pins (old style clothes pins). A problem with old style wooden clothes pins is that they are cut so when pushed or pounded into the grou
Reading all the stories about early experiences on Top Band brought back some memories. I checked old QSL cards and log books for dates etc. I first got on 160 in December of 1961. Using AM and CW wi
Telephone companies that have a lot of drop wire hanging on poles will tell you lighting damage to the drop wire which feeds from the telephone open wire or cable is rather common. The drop wire cons
