I will start with my limitation. At my QHT, the only way that I can get a 2m antenna high in the air is by hanging it from a ~100ft pine about 30 feet from the house. At the moment, I have a 'slim jim' modified J-Pole made from 1/2" copper pipe suspended from the tree. The top of the slim jim is exactly 72 feet in the center of the state of South Carolina. The antenna is fed with LMR400 which is connected to a Yaesu FT-2980 80w 2m radio. This configuration gives me the following: repeaters within 35 miles in all directions simplex users with similar height advantages to mine within 25 miles repeaters within 85 miles are reliable from north-northeast to west-northwest the change in temperature the first couple of hours after sunrise brings me repeaters up to 130 miles NNE to WNW reliably My record DX contact during inversion is 258 miles (I've only been doing this a couple of months) My goal is to increase my reliable range, making me less dependent on weather (inversions). Height cannot practically be increased; the limbs at the top are just too small and close to the trunk. I posed all of this to some local amateurs who advised me that a higher gain antenna might do the trick. The two antennas with the highest gain that I can find are the Comet GP-9 and the Diamond X510HD. I have ruled out directional antennas as the antenna must be hung, not mounted. Would it be possible to hang either of these antennas, or must they be mounted from the base? Also, since both of these antennas are 17 feet tall, the enter of both antennas would be about 8 feet lower than my current antenna In addition, any feedback about whether or not this will help me achieve my stated goal or not would be appreciated.
