Review on RoadPro RP-302MAX: Extra Heavy Duty Chrome Plated 3/8 x 24 Maxi Antenna Stud with SO-239 Connector – Premium Quality for Optimal Connectivity by David Moreno

I bought this bolt because I broke two normal antennas with the larger standard antenna. The only reason I didn't give 5 stars was that the so259 center port is not fully supported by the insulation. I don't expect this to be a problem but with the description 'Extra Heavy Duty' I would expect it to be fully isolated. No problems with purchase and delivery.
