HI-Gain SAT Ant Instructions

If anyone is interested, here's how: 1005 divided by the frequency in MHz will give you the length in feet. Multiply by 12 to get the length in inches. For example: a TX freq of 265 MHZ would require a 45 1/2 inch long wire. An RX freq of 250 MHz would require a wire 48 1/4 inches long. The RX freq is almost always lower than the TX freq, so the RX antenna would be slightly longer. (the closer you get to the exact length, the better your gain will be) Use the solid core 12-3 electrician wire that is normally used to wire household electrical sockets and stuff.

Use a BNC plug-to-two BNC jack Tee connector and two BNC plug-to-red and black binding post connectors. Connect the binding post connectors to the tee connector, ensuring that as you look at it, the same color posts are diagonal from each other. ADD 1 inch to the length of each of your wires to compensate for a stripped 1/2 inch, 90 degree bend at each end of the wire that will be inserted into the binding posts. Form each wire into a loop, insert the stripped end into the binding post and cinch down tightly. The RX loop must be on the bottom and the TX loop on top.

Connect to your radio and it's game-on.
