Hi, in the 20 years I've been a ham almost any length worked OK. If you need
only 30 feet, there is no need to use 100'. There was one time though where I
had a lousy SWR on 440 and 2 meters was fine. I experimented with a few pieces
of coax jumpers. It truly did change the SWR. I cut a few inches off the main
coax and all was within the proper range. BTW, the proper way to check the SWR
is put the meter at the antenna. It's pretty hard to do this when the antenna is
20 feet in the air. At the radio is good enough.
Good Luck

Instead of wasting bandwidth on stuff that cannot be changed by the general

chains (E-Bay posting in this NG), how about something that might even be
technical in nature??? How about the answer to this question??.....When
cutting the feedline for a dual band (2m/70cm), for maximum performance, it
needs to be cut to multiples of electrical half wave length. Does it need to
be cut for 2m? or 70cm? a combination of both? or split the difference?

When a work lifts your spirits and inspires bold and noble thoughts in you,
do not look for any other standard to judge by:
the work is good, the product of a master craftsman.
