Instructions:

Reflector / Director

Connections - splice

or crimp sleeve

"Line men's" Splice

Locate the small bag of crimp sleeves (5 +1spare).

After completing the wiring of the Reflector and Director elements the ends must be connected to

complete the Quad loop. Slide both ends through the sleeve as shown in fig 3b. Pull wire through

to eliminate the slack in the wire. Temporarily fold each wire end as above to hold the wire

position. Check the tension in all of the sides of this element, making sure that the arms are

"square" and in line. Make an adjustment at the sleeve and if satisfied Crimp, or solder the element

wire into the sleeve. This technique allows you to get the element wire tension correct without

committing to a wire wrap or crimped connection.

Additional Notes on feeding:

Separate lines are to be preferred over the simplified "Single FEED LINE" method to a

common junction 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.
