102" mobile antenna
Any suggestions?
Thanks, Eric |
Yes, they exist. How's that?

The message is titled 102" mobile antenna. It should ring a bell about being
a MOBILE. That should ring another bell that makes you think it's for a vehicle. Suggestions were expected from people who have had experience with these, or can say something about these type of antenna. Is it that hard to understand? But ok, I'll explain a little further. I'm installing a cb radio in my jeep, and I will be in very remote areas, therefore I considered the full quarter length whip. Any suggestions on what antenna to get?

Sorry never owned either so can't say which is better -- maybe some one else
can help. Two considerations though -- radiation efficiency and mechanical integrity. I suspect the radiation efficiency is about the same between the two. Some offroad vehicle owners might comment on the mechanical integrity as far as banging into tree branches etc. 102" whips are usually spring mounted so have a certain amount of give to them. Maybe a post at rec.radio.cb will find more responses from actual users. Also a CB shop will probably have words of wisdom. -- 73 From The KeyBoard ----------------------------- "Eric" wrote in message . net...

I got a stainless steel 102" whip (one piece) at radio shack, for about $15.
Will see how it works... Thanks for all the replies and sorry for the multiple replies from my part, my provider was timing out and I tried a few times...

I'm installing a cb radio in my jeep, and I will be in very remote areas, therefore I considered the full quarter length whip. Your initial question was pretty vague.. :) The steel whip is pretty robust. I used to run one, with the spring removed so it was resonant on the ham 10 meter band. Good results worldwide with 25W on sideband. As I said, watch the short overhangs! :) Otherwise, there isn't much to break on them, and no protruding coils to hang in the brush. Now, I run a cobra 6000 centerload, and a Diamond SG7900. A 102" whip isn't practical, on a roof mount. At least not when your roof is 7' off the pavement. The cobra is mag mounted, so it fails soft, but still, the fall isn't good for it, or the car. The 7900 dosen't bend, it breaks. If it didn't have such great gain, I wouldn't put up with it. http://www.inchase.org/outflow/event...2/f5Mount.html This is the 7900 mount. I had a bit of a surprise with floopyness of the roof metal, but that was easily solved, once we found the right bit at the hardware store. The problem with antennas, is that you can't get high gain, omnidirectional, and reasonable bandwidth, without also picking "large". Keep the antenna as clear of the vehicle as possible, and make sure that what it's mounted to, is really grounded. Bumpers sometimes aren't these days, and few want to dig the hole in the side panel for the old ball mount. (Side panels aren't what they used to be either!) |

Words of possible wisdom at URL: http://www.olypen.com/craigh/antennab.htm Discusses merits of SS vs Fiberglass flexing and also which is the better radiator. Watch which he's talking about. You can get a straight steel whip. You can get s straight fiberglass whip. You can also get a short fiberglass whip. The short versions are compromises, to the degree that they are shorter. A 2' antenna is not as good a radiator as a 3' antenna, all other things being equal. Usually, you end up mounting where some portion of the antenna is shadowed by the vehicle, unless you do a roof mount. In this case, a shortened antenna suffers even more. There won't be much difference between fiberglass with a copper wire, and stainless steel. The copper is more conductive, but it's thinner. Steel is more resistive, but larger diameter. Me, I'd take the steel. Fiberglass breaks, steel bends. |
Question......
Why is it that some people say you need to add a 6" spring to a 102" whip in order to match it? Could someone explain this? If you do the math (234 / Freq. in MHz = 1/4 wave) it ends up being 103.29" @ 27.185 MHz (CH 19 mid band) which if you add the mount, say a 1" stud plus the insulators, it comes out pretty close to 103.29" not counting the inch or so of exposed coax at the connection. I've never been able to add a spring (rat shacks were shorter than 6") without having to cut about the same amount off the whip in order to keep the SWR reasonable. Thanks, Bill |
Eric, We were serious in our questions regarding what do you want to
know about the 102 inch whip. Many of us are amateur radio operators who use the 102 inch whip in a variety of modes and on many frequencies different from the CB Band. The 102 inch whip in your application will provide very good antenna. However, your ground wave will be somewhere around 10 to 15 miles. The antenna will not improve the ground wave. You may encounter some 'skip' conditions but these are not reliable for communications. Eric wrote: The message is titled 102" mobile antenna. It should ring a bell about being a MOBILE.

Eric;
I wish to endorse the comments below. For years, until 1958, 11 meters was a ham band. The FCC in response to requests for a cheap and easy to use radio communications service created the "Class D General Radio Service" and removed 11 meters from amateur service. At the time many (most?) amateur radio operators were, to put it mildly, *issed. Some still have to get over it. However a very large percentage of present hams either started as or are also CBers. Ignore any and all negative comments about CBers. While some comments are justified understand that not all hams are pure as the driven snow either. CB radio does have a valuable place in the scheme of things. One of the benefits of amateur radio is the knowledge one gains along the way to acquiring a license. As my flight instructor told me when I passed my pilot's test. A license is just the start of your education. I hope that you haven't taken any offense to the casual comments about your initial request for help. Your question was rather vague. The information that was given is good and should get you started along the way. Having said all that I have I encourage you to look into the wonderful world of amateur radio and acquire an amateur radio license. With the probable demise of the code test gaining a license has never been easier. No matter your interest, you will find something in radio electronics that will interest you and give you a lifetime of activity. Dave WD9BDZ Dave VanHorn wrote: "W7TI" wrote in message ...
