thats right you can use the a99/i-max2000 as a scanner antenna and a darn good one at that.i don't own an a99 or an i-max 2000 but i do have an i-max 99 witch is a cross between the two and i've used it on my radioshack pro 89 scanner and in works GREAT.i highly recomend that you try it. now i don't think it will out perform a dedacated scanner antenna but if you don't want or don't have room for two antennas this will work good but don't try using your scanner and cb at the same time. |

The A-99 will work as a lowband scanner antenna ( 30-50 mhz ) However it will be next to worthless on 800 mhz. Now a discone AND a A-99 using the discone for 144-900 mhz ( MOST DISCONES ARE NOT ANY GOOD AT 29 mhz ) and the a-99 for 29.600 - 54.00 would be a good combo. another very good lowband vhf antenna is a cut down skylab. I used one on 52.525 for years untill a lighting bolt FRYED it. |

well i've been able to recive just fine with it on vhf hi and uhf (144-155mhz and 440-465mhz).here in louisville not many agencys use vhf low so i don't know how well it performs on that band and i don't have a 800mhz capable scanner so i haven't been able to test it on that band but i know it works on the bands they do use here. |

Pretty much any length of wire will work better than the antenna that comes with most scanners and any antenna will work best on it's resonant frequency where it has the most gain.
I agree with Bruce that you can do better on higher frequencies though. I have a couple different discones from Radio Shack and they work well from 50 MHz to 900 MHz.
If you have a TV antenna on your roof and haven't connected that to your scanner then you haven't lived. Most TV antennas are of a log periodic design which have a fairly wide bandwidth and moderate amounts of gain. In areas where most activity is on UHF and 800 MHz a vertically polarized UHF TV antenna will give outstanding results. |

just a throw back...the a99/imax antennas work on vhf 130-180 because it has a resonating section for the WX recive feature on most radios...in fact, a gentleman here in my area uses his a99 as his omni-antenna for the 2 meter band, works quite well too. |
