The 6m/2m/70cm antenna (labeled with "857" on the window feed through) is a Diamond V2000A.
2m/70cm have reasonable SWR over the entire bands.
6m is tuned to have lowest SWR at approximately 53.5MHz. It does NOT have acceptable SWR at the low end of 6m. It is safest to stick to the 6m repeaters stored in memory on the FT-857.
You are more than welcome to use it with your own radio if you'd like (100W or less). There is no tuning, but if you operate outside the limits of the antenna you will experience high SWR. USE WITH YOUR OWN RADIO AT YOUR OWN RISK!
