i know it seems that everyone raves about the diamond antennas. imho, although they sometimes work, i believe they also increase the snr <signal/noise ratio>. this is especially true with my portables. i did not notice this effect on a base, but i do have better choices for base antennas. i have also had better luck with the telescoping whips, and the rs 800 meg. antenna. heres a neat trick <although not new> if you have a window/s with a baseboard radiator under it/them, put a magnetic mount whip there. also if you have something metal that you can use as a base foundation for the mag. mount, try putting it at window level. just for safety, if you have kid's/pet's/clumsy people DO NOT use anything heavy as your base <counterpoise>. no sense in hurting anyone. you can also try <if doable> the old stick a mag,mount antenna on the fridge trick. there are several real low profile mobile antennas, that fit this project nicely.
