Anyone familar using a RLB with feed lines & wide band antennas?

I have two runs a cable running to two discone antennas. Attached are screen saves of the scans of each with and w/o a 50 ohm load attached. The pics are labeled "up" & "low" representing the location on the mast of each antenna. All fittings are 'N'. The RLB is a Eagle RLB150N5A.
The cables are;
Unknown (unlabeled) RG8/U: 50' (labeled "upper")
Shireen RFC400: 60'  (labeled "lower")
There is also a 5' jumper w/ a lightning arrested (which I forgot they were there or I wouldn't of included that in the test).

My question is do these scans look 'normal' (acceptable) or does anyone see issues here? I was troubleshooting possible reception issues, the reason for the thread.

Just to be clear, no antennas were attached. The sweeps labeled 'load' were the reference dummy load only.
I'm just interested in the feed lines themselves.
