KX4O 1B-Battery VA Field Day 2015

The 20m AHVD and 40m small loop antennas during KX4O 1B VA field day.

Despite a weak battery and few contacts, our 1B-Battery effort verifies a 40m small-loop and packet-radio NTS messaging using quick deploy antennas.

Hatteras Ham Shack

Hatteras Shack with the Asymmetrical Hatted Vertical Dipole antenna

I took the asymmetrical hatted vertical dipole to Hatteras beach to activate NA-067. I wasn’t very successful, but made a couple QSOs. Despite mixed results, the setting was spectacular. The vertical dipole worked.

Assembling the Vertical Dipole

The asymmetrical hatted vertical dipole (AHVD) provides a quick setup HF antenna at Hatteras lighthouse.

Build this Vertical Portable HF Antenna

This antenna fits into a baseball bag except for the tripod.

The Asymmetrical Hatted Vertical Dipole (AHVD) prototype is an easy to build, portable alternative to other freestanding vertical HF antennas such as the Buddipole.

Asy Hat Vertical Dipole

Three views showing a how a planed vertical need not always be the classic 1/4 wave monopole.

We re-introduce the theory and origins of Cebik’s (W4RNL) Asymmetrical Hatted Vertical Dipole (AHVD) antenna with the hope to facilitate a vertical polarization portable 20-10m aerial for portable operations.
