Install your completed DX Engineering
HEXXAGONAL BEAM Mark 2
with a rotator at a height
of at least 25 feet for very good results. The best overall results are realized with the antenna at 35
to 65 feet.
SWR Testing
The
HEXXAGONAL BEAM Mark 2
should not require tuning. SWR may be checked when the
antenna is at least 8 feet above the ground, however SWR dips may not be under 2:1 or not in the
band. Once the antenna is elevated to a 35 foot or higher operating position, SWR curves should dip
well below 1.5:1 within each band, with much lower SWR likely near the low end or middle of the
20 and 15 meter bands, and lowest SWR around 28.200 MHz in the 10 meter band, however the
G3TXQ broadband version provides low SWR over a wide frequency range. Lower frequency
SWR dips are normal for antennas installed below 35 feet. If any adjustments are desired, they
should be done incrementally and simultaneously with a small changes of driven and reflector
element wire lengths. Example: Tuning on 10 meters is done by trimming approximately 1/4" on
each driven element wire and approximately 1/2" on the end of the respective reflector wire. Extra
Ring Terminals are included in the kit to allow replacements as you trim the wire lengths. Once the
frequency of the lowest SWR may appear below the band, if the SWR is checked before the antenna
is elevated into appropriate position. Reasonable SWR should be the result on all bands after the
antenna is elevated.
Temporary accumulation of moisture or ice on the element spacer ropes has very little effect on
SWR.
Enjoy your high quality, DX Engineering
HEXXAGONAL BEAM
, which should offer years of
trouble free performance.
