BF-L800 Industrial Grade Anti-UAV Signal Blocker with Aluminum Housing

We've been running these in perimeter defense setups for about six months now, and what it does is create a solid curtain of interference across the 700-900MHz and 2.4G-5.8G ranges — the omnidirectional antenna handles sweep without needing a lot of aiming. The 50W output is enough to push through most residential-grade drone electronics, though you'll want to keep it within 500 meters or so for relaible effect.

Actually, the aluminum housing makes a real difference when you're setting this up outdoors in variable weather, since it doesn't corrode like some cheaper stamped steel units we've seen. It's pretty much built for military or government facility work where you can't have a drone getting close to a sensitive event, but it's also overkill for small-scale hobbyist interference zones. The GSM850 and PCS1900 bands are locked in as standdard, but the 2.4G and 5.8G can custmized (check lead time on that) for specific operational needs.

Host dimensions are 60×48×35cm, which sounds big until you realize the 22kg host weight actually stabilizes the unit in wind — we had one on a rooftop during a storm and it didn't budge. The full package with padding comes in at 38kg, so it's borderline for one-person carry but manageable with two. Battery capacty sits at 25A, which should give you roughly 4 hours of continuous operation depending on how hard you're driving the transmitter.

We usually have stock on these, but the aluminum housing and custom frequency work mean lead time can stretch to 20 days or so if you're ordering outside the standard band set. Most buyers go with the full 700-900MHz plus 2.4G-5.8G coverage — the tighter tolerance on the frequency lock is better than what you get with off-the-shelf consumer jammers for this kind of work. One thing people don't always ask: the omnidirectional antenna pattern does have a slight null directly overhead, so don't plan on stopping a drone coming straight down; it's designed for horizontal and angled intercepts.

Package comes in a carton with protective padding, but the housing is tough enough that we've shipped these internationally without damage in most cases. It's not suited for indoor use at all — the power level can interfere with building infrastructure, so stick to open-air installations. 47×36.5×28cm product dimensions mean it fits in standard vehicle transport without special racking.
