Primarily designed to be lightweight and portable, these filters are ideal for use in field operations such as Parks on the Air (POTA), Summits on the Air (SOTA), and Field Days.  They have  been tested at power levels up to 20 watts with SSB, CW, and digital modes.  These  BNC  male\/female filters measure 3.7 inches (94mm) in length and weigh 35 grams. Made with high quality C0G(NP0) capacitors and Micrometals toroids. Small size and low weight make it easy to take with you wherever you go.\u003c\/p\u003e\n\u003cp\u003eThese filters have a 50Ω impedance and are symmetrical, so it's not important which end is the input or output.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCaution: High SWR can damage the filters. The filter should be inserted inline between the transceiver and tuner, rather than between the tuner and antenna. If your radio has an internal tuner, be sure to use a resonant antenna or an antenna with a matching circuit, such as an EFHW (end fed half wave), in combination with the filter.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eFeatures:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDesigned to reject interference from other near by stations operating on different bands.\u003c\/li\u003e\n\u003cli\u003eLightweight and portable design, only 3.4 inches (85mm) in length and weighing just 23 grams.
