I recently picked up a Yaesu FT-857D. For those that don't know, this is an all mode mobile radio. It has 2 antenna jacks, one for VHF/UHF and the other for HF and 6 meters. Now I need an antenna. I see there's an antenna made specifically for this radio, called the ATAS-120A. I am not 100% sure but I believe it' does all the bands of the FT-857D all on one antenna. However I also see there's an auto tuner made for this radio, an LDG YT-100. Now I am torn on which one I should get. I do have a 10/11 meter steel whip that is 108 inches long. The YT-100 is $199.....and the ATAS-120A is over $300. I am wondering if I would be better off trying to use the YT-100 in conjunction with the 108 whip I already have, and save a little bit of $ for something else? What should i do? Thanks in advance.
