Yep....a GOOD screwdriver with a really high-Q coil will run rings around most other short antennas. Especially if you use a capacity hat. But for mobile operation while travelling, that gets a bit bulky and hard to tame, physically. Not at all, Dave. $5 worth of PVC pipe works wonders. http://www.w5dxp.com/shootout.htm -- 73, Cecil http://www.w5dxp.com |

It's those 5-inch coil diameters that give the problem!!! Takes a sturdy mount for those. -- Dave Oldridge+ ICQ 1800667 |

For example I have a telescoping 18ft whip and I was wondering how it might work with it. I have never used a screwdriver antenna before and the whip collapses to a little over 6ft. |

Mobile antennas are limited to about 12.5 ft above the ground. -- 73, Cecil http://www.w5dxp.com |

I know a fellow who put a wire on the end. Just which frequencies you'll cover will vary, though. -- Dave Oldridge+ ICQ 1800667 |
