HF Field Ops Gear-up. Dipole Antenna Tuning. Post #1318.

Here's another great idea for a temporary portable or emergency HF antenna designed for field use.  In this video, GUERRILLACOM designs, builds, and operates an effective NVIS (near vertical incidence skywave) dipole antenna. NVIS antennas are effective omnidirectional antennas that can cover local, state, and regional communications requirements.  This type of low-level dipole antenna is perfect for local nets, roundtables, and "rag chews."  Just design the antenna for the lowest HF band of use, feed the antenna with balanced line, attach a 1:1 or 4:1 current balun, run 50 ohm coaxial cable from the balun to your antenna "tuner", and you're ready to go.
