INSTALLATION SUGGESTIONS
Your Cushcratt\/HF beam is designed and manufactured to gi ve t op performance and troub lefree serv i ce .Theantennawill perform asspe cif ied,
if the instructions a:i d suggestions are followed, and if care is used in assembly and installation.
MAST: The antenna may be mo unted on a mas t diameter up to 2 inches (5.1 cm) .
MOUNTING :When :nounting more than one beam on the same mast, theyshould be mounted at least 1 /, wave-length (of the lower frequency)
away from
other antennas, Ge nerally, it is best to mount these beamsabove tower frequencyaniennas.
LOCATION :Locationoftheantennais very important. Surrounding objectssuchastrees, power lines, othe r antennas, etc .willseriouslyreduce
efficiency.
To minimize the ettects of surrounding ob ject s, mountthe antennaas hig h andIntheclear as possible . If metal guy wires are used,they
should be broken into non-re~onant lengths with stra in Insulators.

ASSEMBL V INSTRUCTIONS
ELEMENT ASSEMBLY: The elements except for the dipole are taPE'(I together.They are progressively shorter from reflectorto directors.Using
fi
gure 1 mount the longest element near the holes for theu-bolts. Next using figure 2 mount the dipole . Now mount t he longer of the remaining
elements
next to the dipole and then mount the remaining element at the end of the boom.
MAST MOUNT: The boom is designed for either vertical or horizontal polarization. Refer to figure 3 and mount the u-bolt to the boom and mast.
When
verti cally polarized, the Reddi-Match rod should be pointing up .
TUNING: The R eddi-Match is set at the factory for 50-ohm and center band operation . If retuning becomes necessaryuse a good qu alitywatt
meter.
It is not necessary to cut your feedllne or p rune It to a particular length; any length cable may be usedwith the beams. However, the cable
should be as short as possible to redu ce feed line losses. Your cable should be equ i pped witha standard PL-259 coax ia l titting, to connect to the
Redd
i- Match, figure 2.
Tune the antenna at your center frequency ; using a 50-ohm feedl in e from your transmitter ,and a watt meter. Connect the wa ttmeter to the
antennawi
th a short length of 50 ohm coaxialcable. Set the wa tt meter for reflected power. If therefle cted power ls high, loo sen thetuning strap
and adjust it slightly In either direction . Movea wa yf rom theantennaand check the reading . If the reflected power Increased, move thestrapback
to its original posit io n and adjust in the opposite direction. If the reflected power dropped , repeat the adjustment procedure until you achieve
minimum reflected power on the wa tt meter.Disconnectthe cable andwatt meter, and tighten the tu ning strap secu re ly. Use the vinyl boot on the
coax
ia l cable to the beam to Insure a weather proof connection. Coat the outside of the alumi num connector threads and the PL-259'swiththe
sill
cone grease provided . Do not coat the connector center pin or socke twithsilicone. Slide the vinyl boot over the connector and against the brae-
ket for a good weather tight connection , figure 2B. Run the coaxial feedllne along the boom and down the mast using electrical tape to hold
it in posit io n.
STACKING FOR MORE GAIN
Two Econo my beams may be stacked for 3dB IncreaseusingtheP14-VPK stacking kit. The kit includesahorizontal support boom, hardware
and RG-59/U
cable harness.
Four beams may be s tacked w it h two P14-VPK kits and a power divider for 6dB Improvement in ga in.
