I know for the most part, the 12' Patriot gets bad reviews. However, I was able to find this at RadioReference.com:

This past Monday, a colleague and I did a fairly involved test. We made a comparison between the Antron A-99 and the ProComm Patriot 12. Both are end fed 1/2 wave omni verticals with the Antron A-99 being 18 feet in total height above the mount and tha Partiot 12 being 12 feet in height above the mount. Tha A-99 is a full mechanical 1/2 wavelength antenna while the Patriot 12 has a loading coil and is 'electrically' 1/2 wavelength.
We started with the basic A-99 ( no ground radial kit ) on a 10 foot mast and tripod in an open field. The radio was a Uniden PRO500d on channel 20 (center band frequency) using 25 feet of RG8/U and standard PL259 (non teflon) connectors. Our field strength readings were taken with a commercial AlphaLab FSM mounted on a camera tripod at 6 feet off the ground. Our readings were taken at 50 yards, 100 yards and 150 yards from the antenna. We used binoculars to view the digital meter readings so our close proximity to the meter would not influence the readings.
The Patriot 12 was then placed on the same mount and all conditions were the same as for the A-99. The same locations were monitored and the readings were identical at 50 and 100. The surprise came out at 150 where the Patriot 12 actually out performed the A-99 by .08 uW/cm2 on the scale ( calibrated in microwatts per centimeter squared) We double checked the results and confirmed the first set of readings. The Patriot 12 seems to have a shallower departure angle for the RF lobe than than the A-99 that we tested.
Both are VERY GOOD performers and for those persons who need a smaller antenna, the Patriot 12 will do an excellent job for you. If space limitations and wind loading are not an issue for you, then the A-99 is a good choice. We know from company literature that the A-99 has a 2 dbi higher rating than the Patriot 12, but our observations made those figures arbitrary.
(This is not a general endorsement for either product. The overall performance in average conditions should be fairly equal between both antennas. However, we use the Patriot 12 in disaster responses because it is easier to transport and set up quickly than the A-99.)
I've been fooling with homemade antenna ideas but have always liked the look of this antenna. Just been scared to get it. Had given up until finding this post. Is there hope for the PAT-12?
