Tuning
An antenna analyzer is the best way to measure the SWR of the 30 meter assembly. The antenna
measurements should be made at the antenna base using a short (5 or 6 foot) piece of 50Ω coax
between the antenna and the analyzer. If you are too close to the antenna your presence can affect
the tuning, if you are too far, the coax length may act as a radial and resonate.
Raise the
DXE-8040VA-1 to the full vertical position. Taking readings close to the antenna also
eliminates the possibility of a long or marginal feedline influencing the tuning or causing erratic
readings.
The 30 meter add-on kit electrically couples to the rest of the vertical but should not have influence
on the tuning of the 80 and 40 meter bands.
Adjustment of the 30 meter add-on kit SWR is done
by slightly loosening the wing nut holding the Hot
Rodz™ and adjusting the length of the Hot Rodz™.
Adjust both Hot Rodz™ equally longer to go lower
in frequency or equally shorter to go higher in
frequency.
Make adjustments in small steps.
Once tuning is complete, firmly tighten the Hot
Rodz™ in place using the wing nut.
