In using ARRL Transmission Line for Windows application:
RG-8X Belden 100 ft @ 50 MHz has 2.5 dB loss
LMR-240 Times Microwave 100 ft @ 50 MHz has 1.7 dB loss
RG -213 Belden 8267 has 1.5 dB loss at 50 MHz
RG-8 Belden 9913 has 0.88 dB loss for 100 ft at 50 MHz. {Due to the
nature of this line having a lot of air content, the reason for low
loss, it is reported to have moisture condensation issues. Thus I
would avoid it for outside use.}
Andrew LDF4-50A which is 1/2" hard line has 0.44 dB loss at 50 MHz
These were just a few I checked. All values calculated for 100 ft, with
a 1:1 SWR at 50 MHz.
I would cringe at the thought of putting up a fine antenna and loose any
performance on transmit and receive due to feed line loss. In my case
I have a 4 element HyGain 6M yagi which is fed with about 75 ft of
Andrew LDF4-50. I selected the 4 element on a 12 ft boom as opposed to
the 5 element on a 12 ft boom. The side lobe pattern on the 4 element
yagi is much cleaner, hence noise off axis is lessened.
I didn't see any polar response plots on their site so I can't comment
on overall performance of the 6OWL6.
