Highest Gain Antenna
GP-9 highest gain antenna in this category better than Diamond and about any other antenna for 2m & 70cm. I have had a GP-6 and it also works very well but not as good as the GP-9. If you want to have the very best VHF/UHF antenna this is the one for you! It also has great robust longevity for high winds. You will be able to get more distance and longer lasting value with this antenna than any other antenna for the same bands.

Better Than Any Other
Had been using GP-6 prior at my location in So Cal had great success in working all local and some distant repeater. Was running and emergency net and was so pleased with the GP-6 so when I moved to UT my antenna did not do well with uninstall my hired removal just threw it of the 2 story roof and it did not survive well but good reason to upgrade to GP-9. It is so easy to assemble and install. Put it up in a high wind area and in the middle of nowhere. Have been getting great reports on all repeaters some as far away over 50 to 60 miles. I think this is better than any VHF/UHF antenna on the market. Am looking forward to see how it performs and endures the winter months
