A Small Hairpin Matching System for Higher Frequency YAGI Antennas

The VORTEX Antenna Systems Hairpin Matching System is a balanced matching system that is simple to install and adjust. This type of match is typically found on YAGI antennas where the driven element is split in the center. YAGI Antennas are typically balanced antennas and are best served with a balanced matching system.

The hairpin match, being a ‘Balanced’ matching system, suits the YAGI very well. It is also easier to tune than other systems like the ‘Gamma’ match. Most YAGI antennas have a feed point impedance lower than 50 ohms. This matching device has enough capacity to match the natural 50 ohm impedance point, thus giving a good match and low SWR when the antenna is fed with 50 ohm coax.

Kit includes 2 x 7.93mm diameter aluminium matching rods, horizontal bar, 30mm square section Stainless Steel U-Bolt and all Stainless Steel hardware. From the dropdown menu choose the driven element tube size so we can supply you the correct size element ‘P’ clamps. Our current range of ‘P’ clamps fits tube diameters of either 12, 16, 20, 25 or 30mm.

If coax is used for the feed-line, a 1:1 ‘Balun’ is normally required. The correct use with a ‘Hairpin Match’ assembly is a 1:1 current balun. Suggested Vortex Antenna System baluns are available here “Vortex Baluns” . The balun output connectors should be selected as ‘M6 Hex Head Bolts’

‘P’ Clamp Information
The kit is supplied with ‘P’ Clamps that are smaller than the tube size to ensure a good tight fit and electrical contact.
