The OWL (Optimised Wideband Low impedance) Low-Noise Yagi is another development of Justin Johnson, G0KSC. Originally the OWL formed the basis of a DUBUS magazine article which found that low impedance antennas need not be narrow band and unstable in wet or icy conditions.

Generally, the lower the impedance of an antenna, the better performance (in respect of forward Gain (Gain) and Front to Back ratio (F/B)) can be achieved. G0KSC extended his development with focus on 12.5Ω versions of the OWL for very good reason; if a 12.5Ω OWL has its split dipole changed to a folded dipole, the feed impedance is transformed from 12.5Ω to 50Ω and thus any 'would-be' matching losses are removed and ohmic loss reduced to insignificance.

While the swapping of a split dipole to a folded dipole within a Yagi is nothing new (generally done on 50Ω split dipole Yagis to give a new, 200Ω Yagi), G0KSC also established performance could be improved further if the whole antenna (including its new folded dipole) was computer optimised as a complete unit. The results have been more than impressive and with the addition of thru-boom parasitic elements and a folded dipole place above/below the boom, light weight and portability have entered into the equation resulting in a excellent all-rounder.

We are happy to spend time with you discussing your requirement. We understand an antenna purchase can be a big investment and is without doubt, the most important part of any station.

The OWL provides solid, stable performance from a compact, light-weight package. The OWL shares many benefits of the LFA Yagi and has a few very unique ones of its own. The shorter OWL models provide stunning performance for their size exhibiting extremely light-weight, compact  and high-performance antennas for both ham and commercial use. The ease of which the OWL can be fine-tuned along with its super light-weight package make it an ideal candidate for varied locations and uses. As can be seen from the SWR plot, of a 13 element 144MHz OWL across the page,  the OWL can stand on its own 2 feet as a performance innovator providing both constant impedance and exceptional levels of return loss too, and not just during dry weather!

Setup and installation is easy with only a simple choke balun (a few turns of coax at the feed-point) being required to complete the feed-line to antenna connection point. With a 50Ω driven element, matching losses are 'zero' while ohmic loss is at an absolute minimum. This means unlike many companies which present performance figures before matching loss, the InnovAntennas OWL presented figures are 'all-in' statistics.

If it is the best in light-weight, portable VHF performance you are looking for, the OWL is going to be hard to beat. Call us anytime to discuss your requirement we are always happy to help you complete your station!

Watch out for the X-Pol versions of the OWL for EME and satellite purposes which will be launched very soon!
