Hi there ladies and gents. I have a question that has most likely come up
here before, and I do apologise if this is visiting old ground. I am a novice limited license holder in Australia and pretty soon I will have access to the 10-15 and 80M bands. I would like to know what you consider as being the best all round antenna for my purpose? I have plenty of room to mount an 80M dipole antenna, although height is a problem. I can go up no more than about 50 feet. I also have a mast and rotator, so a triband yagi is also on the cards. Just looking for decent ideas here guy's. I know the question is fairly open ended, but I would like to consider all my options from those who have all the best knowledge of what works and what doesn't. To wire or not to wire? To beam or not to beam? To G5RV?????? I am running a TS-850, an MFJ 989C Tuner running 100W out of the box. Thanks very much for your time and I really appreciate your response to my questions. Warmest regards 73 de VK2HXY Troy |

Warmest regards 73 de VK2HXY Troy Hi Troy, As you said in your post you will get all kinds of answers. And a lot will depend upon factors that you do not mention.. I.E. what's your purpose, DX, RagChew Local or distance ?? The G5RV does a decent job on 80m but is not the best choice for 10 and 15m.. on those too bands the beam-- yagi or quad would be best if you can get the up at least 25 feet. Dipole is a good choice on 80meters even thought 50 feet is not really high on that band. if you looking for DX on 80 I would put in a vertical with good ground system as well. Just some suggestions, 73 Dave kc1di |

Thanks for the reply Dave. Well my intended purpose is for DX, although
Ragchew is definitely a bonus. I have a 80M (inverted V) about 10 foot off the ground that I am currently using for receive only and am getting great receive results from VK6,5,4 and 3, all coming in when the band is open here with 40 over 9 signal reports, not bad for such a noisy band. So if I can get that up to 50 feet that should take care of 80 for the time being I guess. I guess my questions were intended to get some discussion going for people to offer up suggestions (for and against) for my intended band usage. I have heard that many use the G5RV with a tuner with good results, although there may be better bang for the buck with other wire type antennas, or conversely, am I better running a vertical? You see my quandary? Are there any better brands of antenna for 10-15-20M in a tri-band that I should be looking for? Or rather the question should be, one's I should steer clear of? Thanks again for the advice, that's what the hobby is all about, sharing the knowledge... 73 Troy VK2HXY Sydney, Australia "KC1DI" wrote in message ...

One man's opinion -
Put up a 268'+/- horizontal loop, 67'+/- per side, feed it with open wire/ladder line through your tuner. Get it as high as you can. Suspend the corners of the loop through pulleys so that you can move the feed point along the circumference of the loop. Moving the feed point will shift the lobes & nulls along the azimuth (i.e. rotate the pattern). This will be a good 80 meter antenna for local work & a good DX antenna on 10, 12 & 15. |

Troy,
You really want 2 antennas. 1. A dipole for 80 meters. 50 feet is not that bad; there are many that are lower. 2. A rotatable antenna of some kind for 10/15. At this point, I don't know of any that don't also work 20, but then, you might upgrade. If you want to keep cost down, I would get a 2 element triband beam. These are light enough to mount on a TV rotator. Doing it this way you don't have to mess around with antenna tuners. The money you save will pay for the tribander. I have a Hygain TH3MK4 at about 42 feet. This appears to be about optimum for 15 meters. Tam/WB2TT "Troy - VK2HXY" wrote in message ... Hi there ladies and gents.

You can build a fan dipole for 1, 15, and 80..that would give you the bands you
are looking for..here's a link to one: http://www.hamuniverse.com/multidipole.html I just completed my 80 meter loop but can't comment on the performance as I have to run the feedline through the wall before I can put her on the air. Good luck... Steve kb8viv |

Thats supposed to be 10,15, and 80. Steve kb8viv |

If you simply feed your 80m dipole entirely with 450-ohm ladderline, and run it through your 989c tuner, it should tune the higher bands, as well, without any great feedline loss. Check your tuner manual for feedline lengths to avoid. Or vary the length of the feedline as shown on my web page and enjoy all HF bands without the need for a conventional tuner. -- 73, Cecil, http://www.qsl.net/w5dxp |

Yeah, that 1 megahertz dipole might be a little large for the average yard
