Scantenna ST-2 Coax question ?

[Jakemcgraw]

With my scantenna, i been using commscope quad rg-6, 75 ohm coax cable 30 ft., and the jumper that i usually use with all my other antennas,,My Question, this Coax being 75 ohm, and my Jumper which is 4 ft. of LMR-100, being 50 ohm...everthing works OK, just wondered if this is alright to do, being the Ohm's are different ?...........Universal Radio sells these, I been using them for a couple yrs. works great at keeping stress off the radio ant. jack.

You lose a very small bit of signal due to the slight mismatch, but it is insignificant enough not to worry about.
