im looking for a mobile antenna that will cover 11 and 10 meter without re-tuning...i am currently running a wilson 1000 that covers 26.600 to 27.600 under 2swr...i want an antenna that will cover 26.500 to 28.500 (2 mhz at least) under 2 with out retuning...what are me best options...nothing to huge as it will be going on my roof where my 1000 currently is mounted, if it gets to big but will work beter i have an empty mount on my drivers side rear beadrail that i could use...thank you in advance for your help

Goat,
The screwdriver DOES require retuning to cover that range.
The Van Ordt 'Powr Stik' would easily cover that range without retuning. However, I am not sure they are still being made. I have a 5 foot model around here that I occasionally use for 10m on my truck. It does perform very well. |

My K-40 Trucker that's on a trunk lid mount is listed for 26-30 MHz., has a higher rating than the Wilsons.
It wouldn't surprise me if it would work on 12 meters with a tuner. At $70.00 it seems to be the best bang for your buck.
I have had many mobile antennas and this seems to do a much better job over all the others I've tried, although I've never used a Wilson.   |

ok, back to the 102" stainless steel whips....Aren't they rated for both without having to trim or cut down the antenna? |

I remember checking the bandwidth of my SS 102" whip and spring with my MFJ259 when I first got it, and it showed a surprisingly wide bandwidth. It was useable from 12 meters through 10 meters, but I think it was a little higher than 2:1 on the upper parts of 10.
I think it'll work fine as long as your radio isn't peaked to the point where a high VSWR will fry the final. If you have reservations then just use a mobile tuner as close to the whip's feed point as possible - that's why they're made. MFJ makes a mobile antenna matcher that is basically just a multiple pole switch that adds capacitance. You could play around with the values of the capacitors so you know what switch position you need for each part of the band you're using. I bought one with that strategy in mind, but never got around to using it. |

I remind you of Goat's original post: "i want an antenna that will cover 26.500 to 28.500 (2 mhz at least) under 2 with out retuning"
Using a tuner is O.K., but that still does not answer his question. He clearly said 'WITHOUT retuning'. Again, I believe the van Ordt is the only mobile antenna that will cover that kind of bandwidth WITHOUT retuning, and still perform well over the entire band. |

OK it's the same as a ham stick or the copper wip for about $20. Will it go 26 - 29 without retuning ....... None of these antennas will.
That said I have BOTH a hamstick and the copper $20 6 foot wip and they are GREAT! |

just ran out & checked my predator for ya, goat-even though you said 'nothing huge'. my XL goes down to 26.815, swr's there are under 1.2:1. it goes up to 28.085, so i checked at 27.995, & they were about 1.5:1. not quite sure 2 mHz is gonna keep ya under 2:1, even with the predator. |

i may look into the pred... always liked those ant's but never had a reason to splurge on one...i imagin i could tune a higher center freq and leave the bottom part of the useable band on CB and center it around 27.755 and still leave the top end useable in ten meters at least up to 28.500....whatcha think
oh, and my 102 sswhip with no spring leaves a center freq of about 27.555(no joke!!) and about a 1.7 on Ch 1 and about a 2.5 on 28.450 |

Unlikely you will find a wip that goes from 27.000-29.000 without a tuner and if you do let me know since i run ch-20 and 29.600 as well as 144/440 in the car. |

As I said, the Anttron 1700 will do it. I've seen it myself.

The Van Ordt Powr Stiks are wound with 4 individual wires and top loaded. The wires are only connected at the bottom and top, and they have an extremely wide badwidth. |

Using multy rap wires makes sence for band width but I can't find any data on any test of just how wide it is. I know my copper 6 foot and my HAMSTICK 7 foot tuned for 27.100 reaches 2:1 at 28.4.
Any REAL test data on this Van Ordt " multy rap " wip? |

hey goat, just for YOU, i took my S9 & threw it in the truck with the predator. tuned to 2.0:1 on channel 1-26.965, it didn't surpass 2.0:1 til it got up to 29.005 mhz(this was how much adjustability was available without cutting the stinger any further!).....so it HAS swr's better then 2:1 OVER 2 mHz of bandspread...that is on a magnet mount. hard mounted results COULD differ. |

There should be a bunch of posts on the Anttron 1700 from around 2003. It was the new hot mobile antenna. I remember it was hailed as the broadest bandest mobile antenna around. I hate to use this line: but do a search of all the threads on this antenna; then, try one.
