Hello All, I'm looking at installing my 706 G in the truck for HF use and
am looking for suggestions as to which screwdriver antenna (or other?) you would recommend. It will go on a small truck. Thanks! Russ KG6TDX |

Thanks! Russ KG6TDX Russ; I had a High Sierra Pro installed on my Honda Element. It seemed to do a good job until it was the target of an automobile bumper. The antenna survived in fairly good condition. The tip of the whip was bent slightly due to whipping around in the impact. The barrel of the lower unit was slightly damaged but not broken. The plastic weather protection tube was broken at the top where the cap is screwed into it. The only other damage was to the mounting bracket. I used a tiltout mounting bracket on a receiver hitch to hold everything on the car. The bottom of the hinge bracket snapped off at the hitch mount. I have repaired everything and the antenna seems to be working great. I can't speak more highly about this antenna. For range all I can report is making contacts from St. Louis to Indianapolis. I was vertically polarized and the other station was NVIS. The rig is an Icom 706MKIIG. I also am using an Outbacker Perth Plus but I am not really satisfied with it. It could be the fault of the installation, I really don't know. Dave Nagel WD9BDZ |

High Sierra, had really good luck with them. Good performance, solid
construction.

I have a Perth Plus (Outbacker) and I think the antenna works wonderful.
However, I do know from experience that installation location seems to be critical. I used to have it mounted on a ladder rack on an Astro van with its ground wire attached directly to the roof with a small bolt and nut. Worked GREAT! Now it's on my F-150 on a mount I made up that goes into my receiver hitch. I ran a 1" wide ground strap from the truck frame up to the top of the mount, where I attached the antennas ground wire to. Now the tuning of the whip is way off from the marks and I can only get it tuned on 75M through about 17M. Works great when tuned on these bands, but someday I'll miss 15M-10M... Scott N0EDV David G.

I had the same problem with a configuration like that. The ground strap is a radiating part of the antenna and is ground at one end and not ground at the feedpoint. On the higher frequencies, it is an appreciable percentage of a wavelength so the antenna is too long. In addition, the feedpoint is located away from the ground point something like a gamma match. Here's what it looks like: radiating GND---gnd strap---FP---------antenna------------- The solution is to ground the system at the FP feedpoint. For me, that was at the top of my tail gate. -- 73, Cecil http://www.qsl.net/w5dxp -----------== Posted via Newsfeed.Com - Uncensored Usenet News ==---------- http://www.newsfeed.com The #1 Newsgroup Service in the World! -----= Over 100,000 Newsgroups - Unlimited Fast Downloads - 19 Servers =----- |

Thanks all for the tips. I looked up High Sierra, and the factory is only
about 65 miles away from here which would be convenient if it came to warranty work. I'll investigate those further. Russ wrote in message ... High Sierra, had really good luck with them.

Scott;
Thanks for the remarks about your installation. I have not given up hope for my Plus just yet. I think our problem with the receiver hitch installation is the mass of metal on the back of the vehicles. My hatchback and your tailgate. The manual does state that we should keep the antenna as far from large surfaces of metal parallel to the antenna. I am going to try using a mast to elevate the antennas above the top of the van and see what happens. Dave WD9BDZ Scott wrote: I have a Perth Plus (Outbacker) and I think the antenna works wonderful.

Well thats the problem, you have it on a ford. I think you need to buy
another astro Van :) Actually I have that same kind of arrangement on my Astro using the trailer drawbar with a Iron horse 40m stick. grounded to chassis. and it works great!

Russ,
The biggest difference in most of the screwdriver type antennas is mechanical, how it's put together, how well it will stand up under use (and price!). Electrically, most are basically the same except in power handling ability. It's been a few years since I did any investigating of screwdriver antennas so what I know about them isn't exactly current, but I seriously doubt if there have been any great 'break-throughs' in design. In general (meaning that there are always exceptions), pick one that you 'like' the looks of, can afford, and won't tip your vehicle over. All the rest is just advertising 'hype'... 'Doc |

Hello All, I'm looking at installing my 706 G in the truck for HF use and am looking for suggestions as to which screwdriver antenna (or other?) you would recommend. It will go on a small truck. Thanks! Russ KG6TDX May I suggest the Carolina Cyclone antenna? I am the builder of this product and I can save you a bit of money. I build them of .065 wall aluminum, the coils are of black nylon and the wire is #14 tinned copper wound at 8 turns per inch. They are solid performers and come in 2" and 3" diameters. Most screwdrivers are basically the same, but one should avoid those that use PVC coil forms and flimsy contact stock. Mine have no PVC and all parts are machined for precise fit and finish. Before you purchase, won't you visit www.qsl.net/k4kwh . I can save you money on your purchase and give you pleasing asthetics and perfomance as well. The Carolina Cyclone has been shipped all over the USA and are serving well (www.eham.net) . Best Wishes and Happy Holidays, Jerry K4KWH |
