Using a Fan Dipole for Six Meters
I just purchased a Ten-Tec 1208 Transverter to get my feet wet on six
meters. I would like to use my existing W9INN fan dipole if possible. At the present time the fan dipole has three sets of wires from the common feed point for 40/80, 10 MHz and 18 MHz. My plan is to add another short set of wires cut for 50.125 MHz. Since each of the new wires will only be 4.67 feet, I plan to use stand offs and run them close to the 40/80 dipoles. It will be interesting to see if this really works. Any suggestions for the short stand off insulators? Dick, AA5VU aa5vu at arrl.net |

My plan sounds good until the wind blows and I have visions of the short six meter wires getting tangled in the other wires. I would tie them off with additional tie ropes but it would wind up looking more like an extreme Inverted V antenna. AA5VU |

Any suggestions for the short stand off insulators? 18 MHz times three equals 54 MHz. The 18 MHz dipole is likely to detune the 6m dipole. See what the 6m SWR is now. You may not need any additional wires. -- 73, Cecil http://www.qsl.net/w5dxp ----== Posted via Newsfeeds.Com - Unlimited-Uncensored-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 120,000+ Newsgroups ----= East and West-Coast Server Farms - Total Privacy via Encryption =---- |
just try it without the extra wires first, you may be surprised and get a
good match from one of the other wires. "aRKay" wrote in message ... I just purchased a Ten-Tec 1208 Transverter to get my feet wet on six meters.

I happen to have a 7 & 18 MHz antenna; so, I measured the SWR on 6 meters. Got about 2.9:1 at 50.25. SWR at 56 MHz is about 1.2:1. Nevertheless, I have spoken to people on 6m who were using 40 m dipoles. Tam/WB2TT "aRKay" wrote in message ... I just purchased a Ten-Tec 1208 Transverter to get my feet wet on six meters.

It should work OK. You will need a little patience to prune the 50 Mhz
antenna length to resonance. To reduce the coupling between antennas you could allow the 50 MHz dipole to droop a little in the form of a shallow inverted-V. Just progressivly increase the lemgth of the hanging insulating strings towards the end of the 50 MHz dipole. It doesn't matter if the dipole has curves in it. I hope I have correctly judged your setup. ---- Reg. |

Good point. I may hold off until I get the Ten-Tec 1208 and see what I
have with the existing mess of wires. HiHi I don't have an antenna analyser so will have to wait until I generate a six meter signal. Anyone ever tried six meters on an old Ringo Ranger 2 meter antenna? Dick AA5VU I worked Canada on 6 meters with that transverter. Used a trapped dipole for 40 to 10 meters. I doube the ringo would work on 6 due to the way is fed. If it was just a baseloaded (matched) 5/8 wave 2 meter antenna, it might work fine. |

Any suggestions for the short stand off insulators? Dick, AA5VU aa5vu at arrl.net That 17m (18mhz) antenna should do well. I run a bunch of antennas and for local work rather than turning a beam I use a `24ft EDZ with a stub tuning on each wire to match 50ohms. The oddity of that antenna is it looks like a plain dipole at 18mhz according to the MFJ269b. I'd drive that and see what the SWR looked like, it may be fair as is. Owing to the amount of wire it may offer some amout of gain over a plain dipole. Good luck, Allison KB1GMX |

I will then see if someone is close before I start messing with extra wires. The problem with adding another set of wires for 50.125 is how to keep them from getting tangled in the wind. I have visions of them wrapping around the 40/80 set of wires. Stay tuned for what happens. Half the fun of getting a new toy like the six meter transverter will be finding the right antenna.

I will not waste time messing with the old Ringo Ranger. Don't give up on the vertical too quickly. I use both a 6 meter dipole and a 6 meter J-pole, 90% of my 6 meter contacts have been with the J-pole. Some of the more experienced Hams of my acquaintance have told me that DX sort of works outside of the normal vertical/horizontal polarization expectation. I rarely have any occasion for a local 6 meter contact. so am not able to speak about that aspect of the 6 meter band. Harold KD5SAK |

I forgot about the J-pole and I may try one while playing around with the new stuff. Dick - AA5VU |

Harold KD5SAK Experience is that my vertical beam hears far less DX than the horizontal. Occasionally I hear DX on the Vertical that is better but on confirming the other end is also vertical. So it goes. I do have vertical for those times where it may help. One thing I do notice is the noise level of the vertical beam is far worse. For local use the horizontal is usually 2-3 Sunits higher than the vertical. Allison KB1GMX |

Allison KB1GMX Before somebody tells you that polarization is unimportant for a skip signal, your 6 meter observations parallel what I found on 40. I had a 40 dipole and 40 GP vertical. In round table test with stations 400 - 800 miles away, people with verticals preferred my vertical, and people with dipoles preferred my dipole. There were a few people who could not tell the difference. Tam/WB2TT |

Allison, I have heard good things about the Ten Tec Transverter and figured it was time to give it a try. I am a RTTY Junkie and noticed a six meter RTTY spot yesterday. The 1208 should be here on Tuesday. Dick AA5VU The TT I had had a very hot receiver. I had the marage amplifier with the gasfet preamp and when I turned on the preamp I could not tell any differance in the weak signals. The S-meter came up but the noise came up with the signal. I could get the same effect in the audio just by turning up the volume on the receiver. On transmitt, 10 watts or so is still 10 watts. Just a little too low for me on 6 meters. With many of the newer rigs having 100 watts on 6 I think that is the power level to shoot for. For what is it , the transverter does a very fine job. |
