Phasing Lines

Many of our customer’s request custom phasing lines for antennas other than Directive Systems. To be clear, our “phasing lines” are electrically equal lengths of 50-ohm coax and are intended to be used with a power divider. Except on 6 meters, we do not use 75-ohm coax as transformers.

We use high quality double-shielded foam dielectric coax made by Advanced Digital and it is identical to LMR-400. We use high quality PTFE insulated crimp connectors and the rear of the connector is sealed with sealant infused heat activated heat shrink tubing for years of trouble free service.

We are more than happy to make any lines you need and here is the information we require in order to get you the correct lengths:

  • Connector type at both ends (default is always Male Type N)
  • Distance from the connector on your antenna to the boom-to-mast plate
  • Stacking distance between the two antennas

When looking at our Phasing Line part numbers, a DSE5PL would be a pair of 5-foot phasing lines; whereas, a DSE20PL would be a pair of 20-foot phasing lines. For anything not on our list, please contact us.

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 12.5 ohms. . read more
