Four pack with SMA female antenna on radio, including 4 standoffs/spacers. With the radio on the belt, the tip of the antenna reaches almost to the chin, but is flexible and rounded for safety. The signal is weaker than the more powerful Kenwood or Diamond antenna, but much better than the standard Baofeng antenna. They can communicate in simplex over 1/4 mile on both 2m and 440MHz. This is a big improvement. The packaging is stamped for both BNC and SMA but not marked. Revain's photo is true. Part number X002808QYD, made in China. Supplied in a yellow plastic case. I use 2 and will give to 2 other people who need them. DO NOT lose O-rings. Someone else, please measure SWR and EMI. The SWR did not damage the radios. I did not do these measured tests. I used them in the air and other people said the signal was 5x9 ie very good. Good price.
