Diamond, Antron, Solarcon, Etc.? What is YOUR choice for the best BASE antenna, w/GPK or not. I am in the market to purchase a new antenna and I usually get the most sound advice from here.

Rich,
Follow Milkmans instructions, I did and realized that with my height restrictions at home that instead of using my Imax 2000 at a height of 15 feet to the feedpoint, that I would prbably be better off with a Top One Astroplane. Theres some really helpful info in that post.

The best vertical base antenna is the one that puts the most signal on the horizon from your QTH. |

Milkman,
I am currently using a Max-2000 No GPK. Currently my antenna is at 44-foot tip (still NOT grounded, alot of static/noise, getting there slowly with the new install). I have it mounted on a GAP tilt-mount because I live in this *{&^%$#@! deed-restricted developement.
Thanks,
73's, --Rich |

Draft,
With the TIP of your antenna ONLY being at 44 feet this means the LOAD is ONLY at 20'.
This can be what is causing your problems.
You want the BOTTOM or LOAD to be as high as you can get it, either at 18' or preferably at 36'.
If you added a GP kit to your IMAX with the load/base only being 20' off the ground the tips of the GPKit would ONLY be 14' off the ground.
This I WOULD NOT Recommend anyone doing.
If you can raise the BOTTOM of the Imax to 36' and ground everything properly you may find it will solve 99% of your problems.
With an IMAX 2000 try and get the ""Base/Bottom"" of the IMAX 2000 at:
18' = (1/2 wave) (not recommended)
Or
36' = (1 wave}
Or
54' = 1-1/2 ~ wave length.
The higher the better and use 18' increments.
Hope this help's,
Lon

Or, replace it with a Top One and don't worry how high or low it is. |

not that me seconding 833's suggestion means anything, but with only 20' of mast to work with, the TOP ONE antenna is your best friend!
i had mine up on a 15' mast, and still got out great, and no noise.
here is a thread to get you aquainted with this antenna:
http://www.copperelectronics.com/cgi-bin/discus4/show.cgi?tpc=29&post=93094#POST93094
and it costs just about the same as the GPK for the IMAX.
honestly, if your antenna must be low to the ground, you will love the top one antenna.
good luck,
matt |

The best antenna is the one that works for you at your location.
I have antennas that failed miserably where I lived but worked great at a friends place only a mile down the road. I have alos had antennas that barely worked when situated on one side of the house but were terrific when moved to the other side.
Before you buy anything try moving the antenna either around you house or up and down in height. You may well be surprised. |

Good advice, still restricted in height though, it cannot be too heavy for me to tilt-down when I am not using it (between the 20' mast and antennna) due to deed-restriction. Why are those JO-GUNN antennas so expensive, I was looking into the sun of a gun model, $400.00 for an omni? |

If your going to be tilting it down all the time when not using than a A-99 or Imax 2000
straight stick may serve you best, as you
could just lay it on the ground.
A-99 (18ft Length)/ Imax 2000 (24ft Length.) |
