For the main antenna structure, I see no problems at all. Basically the FR4 substrate would be used mainly as a mechanical carrier. A problem may be with the possibly existing transformation element interfacing the dipole to the cable, if designed as a planar circuit. It should be checked for sufficient power handling and losses, too.plane to use it for outdoor dipole antenna.
with peak power of 250 Watt CW
