Additional notes about Feeding quads: Separate lines are to be preferred over the simplified "Single

FEED LINE" method to a common juction point of elements. This is not to say that the "SF" system is

unacceptable, but one must be prepared to accept some SWR compromise when using it If difficulty is

encountered in LOADING and/or SWR with either system.

FEED LINE PRUNING should be attempted as the NUMBER ONE approach when using

the "SF" approach.

Baluns are generally not needed and have proven effective in only a small percentage of unusually rough

situations. Fortunately, the great majority of quad installations perform very satisfactorily without the need to

resort to complicated matching systems, but in an occasional "rare" case of difficulty, the Gamma Match

(either individual or Tri-Gamma) has proven to be a good solution. For Gamma Match information see

historical notes at end of instructions, or refer to Bill Orr's book on Quads.
