These days, affordable software defined radios (SDRs) have made huge swaths of the spectrum available to hobbyists. Whether you’re looking to sniff the data from that 433 MHz thermometer you’ve got in ...
For the longest time now, I’ve wanted to build a real, proper radio telescope. To me, this means a large parabolic reflector, a feed horn made of brass sheet, coat hanger wire, and at least for the ...
Fitting a simple, passive, parabolic reflector around your router’s antenna can focus the signal exactly where you want it. Your network will reach farther, and the addition can even improve your ...
I tested aluminum foil, metal bowls, and a cooking pot on my Wi-Fi router—only one actually worked ...
A practical guide to designing log-periodic dipole array fed parabolic reflector antennas using advanced 3D MoM simulation — from parametric modeling to electrically large structures.
General Dynamics Missions Systems will produce AN/SPG-62 antenna system parabolic radio frequency reflectors for the US Navy under a $16 million IDIQ contract awarded by the US Department of Defense ...
