Building antennas is a time-honored ham radio tradition. Shortwave antennas tend to be bulky but at VHF frequencies the antenna sizes are pretty manageable. [Fjkaan’s] 2 meter quadrifilar helicoidal ...

JACKSONVILLE, Fla.--(BUSINESS WIRE)--Redwire Corporation (NYSE: RDW), a leader in space infrastructure for the next generation space economy, announced today that its L-Band Link 16 Helical Antenna ...

In general, this type of antenna consists of one or more conductive wires wound in a helix (like a corkscrew) around a central support mast. The new "bi-stable deployable quadrifilar helix antenna" ...

The quadrifilar helix antenna (QHA) has emerged as a versatile solution for modern communication systems requiring compact form factors, wide angular coverage and stable circular polarisation.

Virginia Tech issued a press release titled Electrical engineers invent wireless Internet connection. Knowing that wireless Internet connections have been around for a few years, I had to check it out ...

THE most widely proposed hand-held antenna for mobile satellite communication systems is the Quadrifilar Helix Antenna (QHA). The QHA is preferred to the crossed dipole and the patch for its small ...

Receiving a signal from a geosynchronous satellite 22,300 miles out or a GPS satellite over 10,000 miles away is a challenge. Big gain antennas usually are necessary. But that’s just the opposite of ...
