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 />
