Where Jim? I have different types.

Clark, I was referring to the long run from the shack to the beam up the tower. Also curious on your opinion of one type or the other that you have used.
Earlier in this thread Carl was referring to receiver sensitivity in the presence of the antenna background noise. Made me think about possible feedline pickup, and antenna imbalance where the receiver performance might be degraded. The coax used even if low loss might have other characteristics that can degrade receiver performance.
Something we never talk about too is coax terminations with the beloved PL-259. I recall Ozona Bob, W5PYT (SK) who had many exotic antennas. Bob once told me that he NEVER soldered the coax braid in the PL-259!
I don't have many high performance receivers here, but I recall my old Yaesu FT-757 was quite hard of hearing on 15-10m whereas my SP-600 heard signals Q5 that were not detectable on the 757. My Gonset G-50 is the same way over my Icom R-75 on 6M. The Icom R-75 however on 75M performs admirably when my neighbor (100 yards away) is 20KC away running SSB with his amplifier. The SP-600 rolls over dead when this happens.
A few weeks ago I heard you briefly on 15m AM, and you were strong. I think the propagation between here and there is a little too close normally.
