... O Of mobile antennas of course. Unless your participating in a keydown and need some oil cooled coil, you will get the best results with a 102" and they are good (most of them) to 1kw. You will get good results but not necessarily the best results. How so? Give me an example. Unless Jay wants to put an I10K on his truck. Out in the desert he could weld 20 foot of tower in the bed. LOL Power handling aside the 102" stainless steel whip is a good antenna but can be marginally beat by other shorter antennas. These shorter antennas tend to consist of large diameter antenna stock made of brass or copper usually with a chrome plating. They also are center loaded with a large diameter air gapped coil.. One such antenna, and I'm sure there are others, is the X-terminator at about five foot tall. I've never used that brand before, but have used many other base and center loaded units. You certainly can't count on manufactures claims of their products performance. I'll put my 102" up against any I have used in the past any day of the week. Nobody in my town can out talk me on the mobile. |

: I concur. A properly mounted 102 inch whip will and should perform better than any loaded antenna. In theory yes. In practice it may not. A 102" stainless steel whip can be beat by some shorter (loaded) antennas. Wrong. By it's very nature, a loaded antenna loses some power in the loading coil and therefore is not as efficient as an antenna without one. The only way a shorter antenna could outperform a full-length 1/4-wave whip is if it had some way to pull down the take-off angle. So far, nobody has provided any theory or empirical evidence that any such antenna exists, or is even possible. ----== Posted via Newsfeeds.Com - Unlimited-Unrestricted-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 =---- |

Installation on a vehicle is far more influenced by where it is located and the vehicle itself. SO for vehicular installations it is not very wise and prudent to make claims as to which antenna is the best. Given all other obsticles equal, the 1/4 lambda antenna will out performe physically shorter antennae. Then not all vehicles are equal, then comparison becomes more a gentleman's gambit. james |

Nobody in my town can out talk me on the mobile. You made two statements that need to be examined 1. Never trust manufacturers claims (or individuals) 2. You put your 102" up against others. The only problem is that you never have put your 102" ss up against the antenna I am speaking of, and we should never trust the claim of others. You and me included. So how do YOU find the truth? You must make a side by side comparison as I have. Any claims based on anything less than that is just a waste of discussion. |

I said you don't have to believe me, but it is easier to believe someone who has actually stated that he has made the comparisons and has posted the details. What you really should do is make the comparison yourself. We would never believe you, but at least you'd know the truth. |
