2018年6月7日 · The OwlRC SWR meter, encased in a compact wooden box, is powered directly from a 3S LiPo battery—ideal for the FPV community. It comes with a SMA connector and features a color touchscreen, eliminating the need for external buttons (except the power switch).

2019年7月15日 · This "RC Hobby" grade SWR METER, measures the forward & reflected waves to determine the working efficiency of an antenna. The meter can be used to run a full scan from 5.645Ghz to 5.945Ghz to indicate the working efficiency (SWR Value) and Center Frequency of an antenna. An optimized antenna will significantly expand the antenna

2019年8月17日 · To help remove the guesswork you need to know what frequency an antenna is tuned for. Some antennas have a flat response across the band while others may be more suited to the upper or lower frequencies. OWLRC have released a versions 2 of their FPV SWR meter which will show you how your antenna performs.

Features: This RC Hobby grade SWR METER, measures the forward & reflected waves to determine the working efficiency of an antenna. The meter can be used to run a full scan from 5.645Ghz to 5.945Ghz to indicate the working efficiency (SWR …

Comparison of Attenuation (dB) of 2006 TLW Results to 2014 TLW Results for 1:1 SWR, Coax and Window Line (WL — including two types, 554 and 551, in 2014) and Open-Wire Line (OWL) Frequency

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!

2025年2月12日 · Es kann zum Messen von HF-Signalen verwendet werden und verwendet 6 LEDs, um die Leistungsstärke und den SWR-Bereich des Signals anzuzeigen. 3. Es wird zum Testen des Signal-Rausch-Verhältnisses von Kurzwellenfunksignalen mit einem Frequenzbereich von 3–30 MHz verwendet.

What is different about the OWL? The OWL is very unique, it produces traditionally high gain and F/B (Front to back) properties of older low impedance designs while producing wide bandwidth and clean patterns too. What do these differences mean? First of all if an antenna has a wide and low SWR curve, it will be much more stable in wet conditions.

Una Yagi OWL (Optimised Wideband Low Impedance – Banda ancha optimizada en baja impedancia) es una Yagi desarrollada de modo distinto de las características de banda estrecha normalmente asociadas a las antenas de baja impedancia.
