Scott:
You neglect to tell us about the splice, and the frequencies of
use. Let's assume that it is a connectorized splice. You'll never see
it (electronically), or care about it, at frequencioes below 30 MHz. At
frequencies under 7 MHz, you could use a VE1ZZ splice and still not
notice it. VE1ZZ brings the two pieces of hardline vertical and ties the
shields together with a stainless steel hose clamp. The two center
conductors are soldered with a small copper jumper. The coax is
weather-protected by putting them in an inverted two liter soda bottle.
Trust me, VE1ZZ is loud, and he can hear.
Do it. Enjoy it. Good luck. -- Fred K1VR
P.S. Yes, commercial installations do wind up with 35-50 foot pieces
extra all the time. $100 of wastage on every job is far preferable to a
shortage once a year.
