The Titanium Satellite C240 BLUE C-Band LNBF is a perfect solution for filtering out interference, which can cause video pixelization, audio break-up or even complete loss of reception within the 4000 - 4200 MHz satellite downlink band. The dual output C240 LNBF model incorporates the latest in filter technology to attenuate the interference caused by 5G, RADAR, wide area WiFi, WiMax, 4G LTE and 5G types N77, N78 Low and High Bands. The C240 steep front-end signal band pass filter and narrow frequency range amplification can provide reliable reception even in areas with strong local and adjacent frequency interference. The dual (2) outputs are isolated and individually polarity controlled using standard LNB power switching (Vertical - 13Vdc / Horizontal - 18Vdc). The C240 with the heavy cast aluminum mass and thick wall housing sports a glossy white color protective finish. This attractive finish not only looks great, but it also reduces overheating when exposed to direct sunlight. The craftsmanship, quality components and innovative design make the C240 superior to any C-band LNBF available on the market. The C240 is provided with a secure fitting, Royal Blue color feedhorn cover, dielectric slab insert for circular C-band reception and mounting hardware. The included universal flat type three ring scalar is tapped for mounting on button hook, three and four leg prime focus dish designs. All Titanium Satellite hardware is secured with the provided Allen Head type screws and key tool. Important Notice: This LNBF is designed to attenuate signals that are outside the target 4.0 - 4.2 GHz C-band downlink frequency range and overloading the LNB and corrupting the signal IF conversion. The C240 LNBF will not attenuate interference that is occurring within the 4.0 - 4.2GHz frequency range. If the interfering signal source is extremely strong and nearby, 5G attenuation filters may not provide enough reduction to eliminate the problem. Operators may also need to provide physical shielding between the interference source and the satellite dish to block the path of the interfering signals. Examples of shielding might include: Relocating the dish behind a building or wall, installing an RF "fence" or attaching side RF shields on the edges of the reflector. Know the source and frequency of the interference before you make your purchase.
