Yes, there are actually several UHF models with different levels of gain, the PD201, PD1150, PD400, PD1151, PD455, and PD755. The VHF models were PD200, PD220, PD620. The 200 antenna is the oldest original with .341 copper tubing as elements each half wave stacked as a colinear array and about 20ft long. The 200 is a light duty narrow bandwidth (only maybe 2 MHz wide). The 220 and 620 use .811 copper tube elements also stacked together and using 5 elements wit a 1/4 wave shunted section on top and a large matching transformer at the base that uses a set of sliding rings for tuning. The value is probably good if they are in good shape, if the fiberglass is old you can apply some marine paint but be sure it is non metallic of course.
