Some help on clarifying 300 ohm twin lead question. At the local hardware
store and RS there is the SEMI-CLEAR, the BROWN, and the LOW LOSS BLACK (foam
filled) 300 ohm twinleads. The SEMI-CLEAR states for indoor use, the BROWN
only states non-UL. The BLACK foam filled is heavier and a bit bulkier to use.
Can the BROWN twin lead be used effectively for outdoor feed lines or the SLV
or should only the heavier BLACK LOW LOSS be used?
Note that some books make reference to antenna feed as FLAT 300 OHM TV line.
