... Speaking of tape measures, I have an old mil-surplus Hy-Gain Tape Dipole. Two versions are described at http://www.n2ckh.com/HA4000.htm. That's very interesting and also proving that there is nothing new under the Sun! I'll need to google for the Octopus, though |

That article on the Octopus Antenna is interesting. It is essentially the same antenna described in QST, but construction is slightly different. I suppose mine is a little different as well. For example, I added a place for a vertical whip. I currently use a 4 foot vertical whip to add a fifth band (10 Meters). The ground whip for 20 Meters is a Hustler mast with the kit for extra resonators. I use a 20 Meter resonator plus a 10 Meter resonator to balance the vertical whip. The 4 foot vertical whip fits in the attic with an inch to spare. Even though it does not have whips for 12 or 17 Meters, it can be matched with an LDG tuner. When those bands are open, I make contacts! I believe your description of the Hamstick is correct. Fred K4DII |

: I replied to your message titled, "Spacecraft antennae". I do not know how my reply became a new message titled, "QST". Xnews shows it in the same thread, depending on its thread ID or whatever it's called. Maybe your client sorts only by subject title, though it might have the option to do otherwise. |

Ò^O In Xnews, when I replied just now, I forgot to refresh before looking in another group this thread is crossposted to. My reply showed up there, and not here, because that group was the first one I saw the post in! It won't now appear here (for me) unless I fiddle about with Xnews to make it so. Your message shows up just fine in both newsgroups. -- ================== Remove the "x" from my email address Jerry, AI0K ================== |

email.me: Your message shows up just fine in both newsgroups. Gets posted to both. ![]() it only once, the first time it is read regardless of which group that is. This, and the subject change, are both likely candidates to explain the behaviour seen. There may be more. ![]() |

Two versions are described at http://www.n2ckh.com/HA4000.htm. That's very interesting and also proving that there is nothing new under the Sun! I'll need to google for the Octopus, though I agree with Fred that while wanting a beam at a decent height, there may be some acceptable lower performance alternatives. At least you could use some of those while still pursuing the optimum. I've had good luck with an attic loop antenna strung around the rafters and fed with a tuner. I haven't had a loop large enough to use on 40 and below, but it worked fine on 20 and above. Currently, I use a 14 foot whip mounted on top of a rather large metal patio cover. It is fed with about 20 feed of RG-8 and a tuner. Performance is not bad on 20 and above. I can manually insert a coil to use it on 40 or 80. It is "ok" on 40 and not so good on 80. I have a friend who uses a Butternut vertical. It is on a tilt base, and he keeps it lowered when not in use. His homeowner association has agreed to that arrangement because it is considered "temporary" instead of permanent. Good luck. |
