6 element OWL (Optimised Wideband Low Impedance) Super-Light Yagi for 69.9-70.5MHz

This compact 4 element 70Mhz LFA provides stunning performance across the whole 4m band (69.950 - 70.500MHz). Hard to beat with a direct 50 Ohm feed-point and no matching losses!

Improved Performance

The antenna is another fantastic design. A low impedance Yagi provides excellent performance. However, traditionally, low impedance has meant narrow band, the OWL has been developed to have very close element spacing, this has increased the stability of the OWL over traditional low impedance Yagi’s. Additionally, the OWL has been optimised for a 12.5 Ohm feed point impedance (with traditional split dipole). With the split dipole swapped for a folded dipole, impedance is now a cool 50 Ohm so again (and as with all Yagi’s no matching device is needed!

Multiband, Performance-Busting Design

This antenna is made with a 1/2inch (12.7mm) and 3/8inch (9.525mm) diameter tube OWL loop and 3/8inch (9.525mm) elements with a wall thickness of 1.6mm. high performance for many years to come. Boom is 1inch.

The antennas are constructed with the best quality materials in order that the best mechanical construction can be achieved, even a digital caliper is used (with an accuracy of .01mm) to measure the elements during production to ensure they are within 0.2mm of what they should be.
