Loss figures are approximate; consult cable manufacturers'
catalogs for complete specifications.
In outdoor installations, be certain to weatherproof all connectors thoroughly, as
water entering a coaxial cable will cause losses to escalate rapidly, thus diminish-
ing your communications effectiveness. The use of the shortest possible length of
the highest quality coaxial cable that fits within your budget will ensure the best
performance from your FT-90R.
