All just a guess on my part, but defendable. For most things I would opt
for a well designed and built discone myself.

If your receiver had a front end with good dynamic range the discone might
be ok. Most scanners do not have particularly good dynamic range. The
discone will be fairly efficient in the FM broadcast band and also on some
TV channels. That may overload the scanner and result in poor performance
all around. It depends on how close the broadcast transmitters are to your
receiving antenna.

A five foot height difference can be significant if it allows the antenna to
clear nearby obstructions.

For most purposes a good grade of RG/6 like Belden 9116 performs well enough
that changing to 9113 will not result in a significant improvement. Quad
shield RG/6 has the same loss as ordinary RG/6 according to the Belden
catalog.
