antenna. Secure with the 1-1/2" U-bolts, 5/16” stainless steel lockwashers and nuts. Do not over-
tighten as severe boom distortion and subsequent weakening can occur. 2” U-bolts are supplied for
attaching plate to your mast.
9. When the antenna is installed in position on the mast, the main feedline can be attached and sealed
at that time. REMEMBER to support the feedline at the antenna boom and on the mast. Leave an
adequate feedline loop for rotation around the tower. When stacking this antenna with other HF
models, maintain a minimum 5’ of separation; more if practical. Mount horizontally polarized VHF and
UHF antennas at least 40” above or below this antenna to minimize interaction.

INSTALLATION AND STACKING INFORMATION
A
. A mast or cross boom that is mounted to this antenna
in the element plane
must be non
conductive (fiberglass, etc).
B
. To protect your investment in this high performance antenna, always use high quality coax and
connectors. Old, corroded, or poor quality materials are common sources of
serious
performance
losses.
C
. If possible, test the antenna, connectors and feedline BEFORE installing to your mast or tower.
Set antenna on a tall wooden or fiberglass ladder or temporary mast. Check for continuity and
match across the bandwidth. It should be similar to rated specifications and plots.
D.
STACKING REMINDERS:
1. All driven element blocks MUST be oriented to the same side of boom.
2. All boom-to-mast plates MUST be mounted at the same point on the boom.
3. Feed / phasing lines MUST be of equal electrical length or multiples of 1 wavelength in order to
maintain equal phasing in the array. Improper phasing can severely deteriorate performance.
