Bolster your TV antenna's performance and enjoy improved over-the-air reception by adding a Philips LTE Filter. This compact filter features TruAmp™ Technology that blocks 4G/5G LTE cell phone and transmitter frequencies that can cause intermittent channel loss, pixilation and overall reception disruption while allowing lower 5-608MHz frequencies to pass through. Setup is quick and easy. The LTE filter has an F-type coax cable jack and port that allow for in-line installation with your existing antenna setup – no hardware or external power supply is needed. This LTE filter is designed to provide you with consistently clear, pure reception of in-range HDTV channels and work with indoor and outdoor passive and amplified antennas. It may be especially helpful if you live in a metropolitan or suburban area where cell phone towers and mobile device users are in abundance. Clear the way for improved reception and a stellar entertainment experience by adding a Philips LTE Filter to your home entertainment system.
