Rotating the mast works well for the 8 foot and 16 foot standard masts<br />
on the Buddipole tripod. The shock-cord masts can also be rotated under<br />
the VersaTee, but since they are solid, one-piece masts (after assembly),<br />
you will need to rotate the entire mast, not just the top section as with<br />
the standard masts.<br />
The Buddipole is supplied with a length of coax<br />
terminated with a BNC connector on one end<br />
and two banana plugs on the other. The<br />
banana plugs mate to the red, blue, and black<br />
mounting points on the front of the VersaTee.<br />
The red banana plug is connected to the<br />
center conductor of the coax; the black<br />
banana plug is connected to the shield of the<br />
coax. A set of ferrite beads surrounds the coax<br />
near the banana plug leads to help keep RF<br />
energy off the outside of the coax.<br />
For a standard dipole configuration (as described in later chapters),<br />
connect the red banana plug into the red<br />
connector, and the black banana plug into<br />
the black connector. Secure the coax to the<br />
mast with the supplied Velcro strap by<br />
threading the end of the strap through the<br />
loop, tightening, then securing the strap end.<br />
Antenna configurations that use the top tap<br />
(vertical configurations) should have the red<br />
banana plug connect to the blue connector,<br />
which is in turn connected to the top<br />
element.<br />
An alternative to using the standard Buddipole coax is the Triple Ratio<br />
Switch Balun (TRSB). The TRSB is a plastic box with a three-position<br />
switch on its face, and a pair of BNC connectors, one on the top, and<br />
one on the bottom. The top BNC connector (closest to the switch) is the<br />
output of the TRSB; the bottom BNC connector (furthest from the<br />
switch) is the input of the TRSB.<br />
The TRSB is superior to the standard feed line in two ways:<br />
1. The TRSB contains a switch connected to a transformer inside<br />
the unit. The transformer provides either a 1:1, 2:1, or 4:1 ratio<br />
impedance match based on the switch setting. That is a<br />
complicated way of saying that the TRSB can match a radio that<br />
