PRO-67-B V.2.S
PREPARING COAX FOR PHASING LINE HOOK UP
< > Cut insulation on coax back 2-1/2" and form the braid of the coax into a leg of the line. NOTE: (Make sure the
leads are 2-1/2" long including the #1021 solder lug! This length is critical.)
< > Once the coax is in the form of a “
Y
”, tape junction, (area where the coax stops and the two lines of the
“
Y
” start), with a good 3-M type electrical tape. This will seal the coax from the weather.
< > Cut the insulation on the “HOT” or center of the coax line, back 1/4" and solder one of the #1021 solder lugs to the
exposed end of the center section of the coax.
< > Before soldering the #1021 solder lug on the braided section, twist braid to ensure you have a good section of line.
< > Solder #1021 solder lug onto the braided line. Be careful not to over heat the braid line to avoid the melting of the
insulation covering the center section of the coax.
USE OF RF CHOKE
< > You (may) want to insert a R.F.. Choke into the coax line to eliminate any RF on the coax line. (This choke is not a
requirement.)
< > To make the choke, coil the feed line (10 turns in a 10" diameter) right after the point where the coax attaches to the
phasing lines. Tape the coil in three places to keep the coil in position and then tape the completed coil to the under side
of the boom directly under the feed point on the phasing lines.
DO NOT USE A BALUN!
