Ok, I have been reading up and tring to figure out what I can buy thats better. I have a PDI407-ar splitter/amp. It says 54-1000mhz forward gain 7dbi, it has 1 input and 4 outputs. I have been using it for about 2 years and it helped the distant signals. But now I want more... I have it installed about 1 ft. from the scanners which I know is not as good as one thats on the antenna. Thats where the questions start. I would like to spend under $60 for a new one, but want better. I have a diamond discone about 25ft up with 40 ft. of LMR400 to a 796D and a Pro-97. I live about 1 mile from the Delaware bay in south jersey. I listen to everything from local vhf to milair uhf and want to get the distant stuff. I do have a wilson yagi 800mhz about 20 ft. for trunked systems. Any help on what exact unit to buy would be great. Thanks again.
