What are power dividers and phasing lines and how are they used?
When you want to stack antennas for higher gain/sharper pattern, the antennas must be fed in phase for the two signals to add properly. When you connect two 50 ohm antennas together, the impedance drops in half (ohms law). If combining four antennas, the impedance drops to 25 ohms. . read more
We offer our power dividers with a “high power” option. A normal female type N is “rated” at 1kw 500 MHz. Due to the size of the center pin and the variations in contact resistance of the center pin, running more than 1kw in continuous carrier modes such as WSJT, can cause extreme heating in the connector and possible failure. Our “high power” divider use a female DIN connector on the input side to minimize the chances of failure. The cost difference is $25 over a standard power divider and are Special Order.
We also offer Commercial Power Dividers, which are Special Order. The 2-Port are $150.00 each and the 4-Port are $175.00 each.
