Len, I'm not sure what a "PD220-N" antenna is, since the PD220 antennas listed in my Celwave catalog have a digit after the hyphen. Anyway, the side mount kit for a PD220 antenna is the PD503. It is adjustable to mount the antenna between 6" and 7' away from the tower. The PD556 is a shorter version that is limited to an offset of 3'. Both of these kits mount on tower legs up to 2.375" diameter. There are other kits for larger leg diameters, up to six inches.

I just purchased a RFS PD220-N to be mounted on a Rohn 45 at the 170 foot level. (190 total to the top) I will be replacing this antenna with a Brand New Comtelco BSLL150-XL3 which has performed horribly. What a BIG MISTAKE! Here is my question: We currently have a lower base dual side arm bracket mount that slides in and out from the tower with a small vertical pole for the bottom brackets for the base of the antenna. What are the correct upper insulated side mounts to protect the antenna from swaying in the wind? RFS PART NUMBER? How many are actually needed? Are they ordered by length or are they adjustable like the lower base arm? We can top mount the antenna, however I dont want the antenna to crack from the winter wind and severe ice in the NYS mountains. Also, There are 2 towers the same height at this site. Literally right next to each other. Should it make a dirrerence in polarization if the top of the antenna clears the top of the tower? Should we make the tip clear or not? Input needed.... Warm Regards, Len N2LEN
