Assuming you are using the correct type and amount of ferrite beads, the
coax type will not change the attenuation one bit. 50 type 73 beads should
do OK on 80 and so so through 160 meters. However, I use 100 so that the
160 meters for a greater margin and more de-coupling. These receiving
antennas are very sensitive to feedline coupling which really can degrade
the inherent performance.
