I am looking this GP antenna, thinking about bringing the Yaesu 2900 in the house and mounting this on the roof 2 stories plus another  15 or 20 feet..My question is will I need a tuner with this and or would a tuner help using the 2900 and maybe the handheld ft60 and uvr5a handheld..what I don't know is, can an antenna tuner help any more even when the antenna is tuned to the band you want...I will eventually get a tuner for HF radio but not sure if it would help to get it now.

Don't bother with a tuner for 2m and 440. Use the best grade of coax you can afford. The bandwidth of antennas for those bands is such that no adjusting of the antenna is necessary, and if there was a mismatch, putting a tuner at the transmitter end would not help. Just connect the antenna and enjoy.

I have one on a 15 foot piece of PVC schedule 80 pipe total height is 20 feet. It works great. No tuner is necessary with this antenna. On 2 meters it is flat about 1.7 to 1, on .70 cm it varies from 1.5 to 2.5/. I use a 30 foot run of RG8X cable. I am using a Yaesu FT-4700RH, and I can hit all the repeaters and anyone I can hear. This is a great antenna for the price. Like someone said hook up your coax and have fun. That's what I did.
