Hey Cooter, just be careful when dealing with such Hi power equipment, the massive RF could hurt you! 
Cool, that will work but i would of fitted an SMA or BNC / TNC socket instead due to the size, You could still attach your normal pl259 plug you would just use an adapter but if you can secure that big so239 on there that's good and fully sik no adapters required..
P.S Id have no chance doing any of that nor would i try.. lmao
