New Performance Plus Model - Increased attenuation for improved and stronger N78 & N77 low band - 5G rejection filtering.The Titanium Satellite C23Performance Plus 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 3800 - 4200MHz satellite downlink band. The Dual output C238 LNBF model incorporates the latest in filter technology to attenuate the interference caused by 5G, RADAR, wide area WiFi, WiMax and 4G LTE. The C238 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. Each of the two outputs is independently polarity controlled using standard LNB power switching (Vertical - 13Vdc / Horizontal - 18Vdc).All Titanium Satellite products are factory line tested multiple times to assure specification compliance and performance. In addition, all products are inspected by an independent third party service to insure complete manufacturing and performance compliance. Any product found not to meet our exacting "A" grade requirements is either reworked and certified to "A" grade performance or destroyed. All Titanium Satellite LNBFs are provided with a limited lifetime warranty against manufacturing or component defect and frequency drift.The C238 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 C238 superior to any C-band LNBF available on the market. The C238 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 3.8 - 4.2GHz C-band downlink frequency range and overloading the LNB and corrupting the signal IF conversion. The C238 LNBF will not attenuate interference that is occurring within the 3.8 - 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 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. We accept and refund for new and unused or tested defective LNBFs. Our product is not intended to be used as a trouble shooting or system testing device that is returned after testing. We will not refund if our bench testing indicates that a returned product, with defective claim is functioning as designed. When a returned LNBF is tested on our bench and determined to be operating within specification, the buyer is responsible for all inbound and outbound return shipping and handling costs. Returns requests and refunds will only be processed directly from Titanium Satellite. Tested items can be reclaimed within 30 days after we email the results status notification. Unclaimed products will be considered abandoned and may be disposed of after 30 days. Please contact us via Ebay messaging or direct email for technical support or product return requests. We have a 100% Ebay seller rating. We will make every effort to earn your business and retain you as a satisfied customer.
