I think I'd like to try a different antenna for 75/80m, and I'm kinda torn between just buying a new S9v43' Vertical or a DIY 43' vertical wire. I have trees in the back yard to support a vertical wire, but are they pretty much equal other than the store bought one being self supporting?
|
|
I have a 31'.
Just a wire in a collapsible tube. If you're not planning on going "portable" a lot, a vertical wire in a tree is fine. |

A 43' vertical for 80 seems like a recipe for disappointment.

The performance of the antenna to me is impressive. I tested it against my windom that is cut for 80. On average I increased my receive between a half to whole s-unit over my windom on 80. It was a dead heat for 40 and I have yet to test it on 20 or 30. I tested using the pipe as the ground with no radials and with four fifty foot long radials. The radials improved my signal reports to stations on all bands by usually one s-unit vs using the ground pipe itself. I am planning on installing 12 radials minimum for a long term installation. All of this was done with the on board tuner on my Yaesu FT-1000Mp Mkv. Sounds promising, to me. |

I run the DX Engineering 43' because I'm tree deprived here. It's the best antenna I've ever owned,
hands down, and practically had me in tears over the years I wasted on the conventional wisdom that a dipole is the perfect antenna (they always leave out the "mounted 1/2 wavelength above ground" when they say that.) Normally the "big radiator" of a 3" tube helps with bandwidth, but you need a tuner with a 43' regardless. What I would suggest is getting a balun and a SGC unit and putting it at the base of a wire vertical with 16 0.1 WL ground radials, using the tree as a vertical support. Then try it out. You'll always have a use for the balun and tuner, and if it works and you want to upgrade, add the hardware. As for 80M, it's not perfect, but it works pretty well. I think I had the third biggest signal on the nets the last two days on 80M. I'll try to post some pics of my setup later today. |

I'd lose the crappie pole and just anchor the wire on the ground (any weight will do) and put some tension on it
(weight attached to a cord thrown over a high brianch, then cord attached to wire.) Most important part of a vertical antenna is the radial system. Minimum is about 16 0.1 WL radials, ideal is ~32 0.25 WL radials where WL is the lowest band you plan on using. SteppIR has a really good paper on radial systems for verticals that shows the best payoff per length of wire. |

A 43' vertical is a pretty decent multi-band antenna. See the VK1OD article below. If you've got a tree to support it, I'd do away with the pole and just run a wire vertical. 43' of wire is 43' of wire, whether it's on a pole or hung from a tree.
Use a 4:1 unun at the base (balundesigns.com) with a tuner in the shack. Better yet, put a remote tuner (e.g. AH-4, SG-230) at the base of the antenna. For monoband use on 80, you could base load it. See the AD5X article below. Remember that your vertical is only as good as its ground system. What are your plans there? I'd probably put down at least 15 radials. The more the better. You don't need to spend the money for a fancy radial plate - use an inexpensive ground bus bar or a stainless kitchen sink strainer instead. 26AWG wire is OK for 100W but I'd probably use 14AWG if you have plans for QRO. Good luck with it. 73. AD5X Article VK1OD Article |

I have basicly an identical setup, except at the top of my vertical I have a pvc standoff and run an inverted V 70' wire up and over it...attached to another SG-230. This allown me the NVIS capability I need for Texas Army MARS comms. The pvc standoff is to negate coupling with the aluminum mast. Your vertical will keep getting better and better the more/longer ground radials you add. That is my only shortfall on mine as it's attached to my RV and I'm limmited as to the radials I can deploy in an RV park. |

Nice work. I'd trim it for 43' (or 13 meters (about 42' 8") if you're following the VK1OD article) and put it up. You don't need to leave extra length to fine tune it, since it's not going to be resonant anywhere you care about. That length was chosen as a compromise to give reasonable performance on multiple bands.

IIRC, you bought a spool of wire back when?
Ill donate some wire to ya BD if you go that route.

Hey BigDaddy––you own all those trees? If you do, I see a very big wire loop in your future...

Quoted: BD, your house looks like almost every other house.Thanks for the help, Gubernator and VRMN8R. I think I still have enough wire for this experiment, anyway. This is the overhead of my QTH. The back fence is 60' wide and the sides are about 45' long. This is the area I have to work with for the radial system. On the other side of the fence I can put them down pretty much where I want since it's in the woods. http://home.comcast.net/~gregbell/My House Google Earth View Marked Up For Radials.jpg Do you drink at all???????? Id hate to try and open up the wrong house.

I've got a similar setup at my QTH with undeveloped land behind me. I put most of my radials on that side of the fence with just a few running into my yard. It's not ideal but it's what I've got to work with.
Here's a good article on optimizing radial length/number for a given amount of wire: Maximum-Gain Radial Ground Systems for Vertical Antennas |

I'd rather spend the money on an sg-230 and be able to run multiple antenna configurations...than spend money on an antenna which locks you into making that antenna work. Seriously, go to SGC's website and read their manuals. You'll be amazed at the various antenna configurations you can cobble up with great results. Verticals, loops, end fed random length, inverted V, dipole. windom....they're all viable choices that work very well when used in conjunction with an SG-230. |

My plan is to mount it, a couple alpha-delta lightening supressors, a DC bias T and a balun and put it all in a pelican case. So don't discount a SGC unit, and unless you're running power, you don't have to get the -230. I would say you want to get something that can handle slightly more power (the -237 does 40W continuous and I discovered during digital nights I was routinely exceeding that by a significant margin, hence the upgrade.) |
