Antenna? feedline? You loose a lot in RG-58. 6 elements is a start. 15
from a reputable maker can make a huge difference in performance.
Antennas and fat feed lines help both ends. Hygain and crumcraft are not
reputable vhf beam makers. Well, they have a reputation, all bad. M2,
K1FO designs, and DL6WU designs (when made in aluminum, not steel) are
good designs.

I've worked mobiles out to 200 miles without enhancements, beam to beam
should do better.
