If you are going to splice your cable don't use pl259's. Use N-type
connectors. Pl259's are lossy and they have a bad impeadence bump.
They are really 75 ohm connectors. I have several splices (using N-type
connectors) in my cables. Checked them all with a sig gen and a spectrum
analyzer. They all have less than .3 dB insertion loss. 

N connectors are weather proof, and have very low loss. I have no idea
why everyone uses pl259's, they are the worst connector I can think of,
except maybe RCA's.
