I purchased a Baofeng BFF8HP recently, and I am considering buying a JPole Antenna to mount on my roof. I currently have the radio connected using RG-58 coaxial cable to a 26 inch Radio Shack antenna on a vent pipe on my roof (yes, Radio Shack came through for me in this day and age), and I'm wondering how much improved performance adding a Jpole would grant me, and if the Jpole is the best idea, or if I should go with a different antenna. I also would like to know the best coax cable to use with my current situation in mind. If someone could tell me how high I should try to mount the antenna too, that'd be great. Advice on grounding it would be much appreciated as well. One last question, considering I'm planning on buying a 2 meter antenna, is there something I can use to connect and switch between additional antennas that would work with my Baofeng? All help is appreciated, thank you in advance.
