Six Blade Spider for the 4-BTV and 5-BTV only
Assemble the 6 bladed spider using the parts shown. This spider is used on both the 4-BTV and 5-
BTV antennas. The spider mounts on the antenna just above the 20 meter trap.
Three Blade Spider for the 5-BTV only
Prepare the three bladed spider for the 5-BTV. Carefully bend the three blades as shown. The spider
mounts just below the 80 meter resonator.
80 Meter Resonator and Whip Installation for the 5-BTV and 6-BTV
Using the supplied Allen Wrench, loosen the two Allen set screws far enough to allow insertion of
the whip antenna about 4" beyond the set screws as shown below. Snug the Allen set screws in
place to hold the whip in place. During tuning, you will be making adjustments to this length.
Install the Hustler 80 RM Resonator to the top of the 5-BTV or 6-BTV in the
threaded rod that is protruding from the top tube. The whip will be trimmed for
the desired frequency during the tuning.
If you desire to have two frequencies that are far apart (CW -vs- SSB), you may want to have two
whips One whip cut for the lower frequency in the CW area of the band, and another whip cut for
the higher end in the SSB area of the band (Part Number HUS-49-04-80S from DX Engineering).
Tuning of the 80 Meter resonator will be covered in the Chapter 7 of this manual.
