![]() "Bruno" wrote in message ... Hi all, I've had a planning application for a tower turned down which is a real pain. My options are now very limited. I'm in a bungalow with a roof apex height of 18 feet and I'm not allowed to put up anything much above this roof line it transpires, so inverted vees that need to be mounted high up at the feed point like G5RVs are not possible for me. My garden boundaries limit the length of any wire antenna I might wish to put up to about 120 feet overall. On the plus side, though, the QTH is several hundred feet ASL close to the top of the hill and am not overshadowed by any trees or buildings to speak of. What's my best choice for an HF antenna under these circs? (I mostly do CW on 20m & 40m, but would like a bit more band choice ideally if poss). Many thanks. Many thanks. For many years, my antenna space has been restricted or limited. I favor verticals in those circumstances. I used a ground mounted Butternut for many years and it was OK. The grounding system was five heavy insulated wires, each five feet long and terminated in 6 foot ground rods. The idea for that grounding configuration came from a study by E-Systems done in the 1970s. Currently I use a 16 foot vertical mounted on a rather large metal patio cover. I feed it with 20 feet of coax and do the ATU inside the shack. I'm currently thinking about adding a remotely controlled ATU at the base of the antenna. For mobile use I have an Outbacker, and I have tried it on the metal patio cover. It works, but is marginal. If you get stuck with a mobile sized antenna, I'd recommend a bugcatcher. If you can handle a 30 foot vertical (advertised by MFJ and others) it might work well with a good ground. If the real estate is limited for ground wires, just do the best you can, and live with it. If your restrictions do not allow a permanent 30 foot vertical, you might get permission to tilt it down when not in use. Good luck! Wayne W5GIE |

I have worked a few stations on 20 M that are using a vertical about 43 feet tall. I think that will exceed the heigth that can be installed at that location, but if not, something to think about. If the band is in good shape, it is possiable to work with minimal antennas. I have worked many mobile stations with the screwdriver antennas on 20 meters and they had very good signals. |

Yes. I meant 43 feet. That was either a typo or a 75 year old brain fart. |

Hustler 4BTV 20 feet, 40, 20, 15, 10 $159 5BTV 23 feet, 80, 40, 20, 15, 10 $189 6BTV 24 feet, 80, 40, 30, 20, 15, 10 $209 DXEnginerring Tilt Base mounting system: $61 to $106 depending on frills. How much for a tower, installation, and antennas? A 43 foot vertical with an ATU at the base will run 160 to 10 meters. There is no city in the US that regulates pounding a piece of pipe in the ground and putting a BTV series antenna on top of it in your back yard. Well, I probably shouldn't say "no" given the flakyness of some politicians. -- Jim Pennino |

My particular "regulations" were not by the city, but by deed restrictions not specifically listed on the deed, but on a document filed with the city that was referenced in the deed as being related to water, electric and sewer easements. I don't live in that city any more, and my current limitations have to do with a very small yard, and very short trees. |
