BoYata 2 in 1 Accessory Lightning Surge Protector Grounding Block 4G LTE Filter

Coaxial grounding block with 4G LTE filter

This coaxial grounding block includes a built-in 4G LTE filter that removes mobile interference between 733 MHz and 1000 MHz while passing TV signals from 5 MHz to 694 MHz. It provides a 75 Ohm connection point for the antenna lead-in cable and a grounding terminal to bond the system to the building earth. The unit helps satisfy NEC sections 250 and 810 grounding requirements for outdoor antenna installations. It ships new with a one-year manufacturer warranty and a 45-day money-back period.

Installers protecting TV systems from surges

The block suits installers who need to ground a coaxial cable entry and filter out 3G and 4G signals that can disrupt over-the-air reception. It is not intended for satellite IF distribution or for data networking cabling that requires DC pass-through or different impedance matching. Buyers who need a surge arrestor with a gas discharge tube or a 300 Ohm twin-lead connection should look at a different device.

5-694 MHz pass band with 733-1000 MHz stop band

The filter’s pass band stops at 694 MHz and its stop band begins at 733 MHz, so any LTE signals above 733 MHz are attenuated while standard TV channels below 694 MHz pass through. This frequency split is the single specification that determines whether the protector matches the local broadcast spectrum and the LTE bands used in the area.
