Presenter: Gerhard (Gary) Spangenberg KF4GGK
Forum Description: As a member of the Pickens County Communications Group ( wx4pg.org ) I developed a presentation that uses WSPR and VSWR measurements to demonstrate the performance of an NVIS double bazooka antenna on a single support ten feet above ground.
Topics to include:
- What is most effective for communicating in mountainous terrain?
- What is the F-Layer?
- What is the best dipole antenna configuration that does not need a tuner, and has negligible impedance variation with altitude?
- Implementation of a 40m NVIS antenna.
- Coverage radius as a function of inverted V angle using a WSPR Beacon.
- Impedance variation as a function of the inverted V angle.
Then followed by Q&A
