Berryville 2015

Berryville KX4O tailgate

The AHVD, Small Loop antenna and some of the usual tailgate “stuff” was made ready for inspection at the Berryville hamfest.

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.

New Choke Configuration for AHVD

Asymmetrical Hatted Vertical Dipole at ARRL Field Day 2014 with new RF Choke configuration.

Shown is a better configuration to fasten a choke to the Asymmetrical Hatted Vertical Dipole antenna.

3D Model for AHVD Antenna

Presented is a 3D E-Drawings rendering of the Asymmetrical Hatted Vertical Dipole antenna.

AHVD – End Caps come in bag of 20

Please note the end caps in the KX4O-000049 drawing show quantity 3, but they come in one bag of twenty. Don’t buy three bags.

AHVD at Richmond Frostfest

AHVD at Richmond Frostfest

The Asymmetrical Hatted Vertical Dipole was on hand at the Richmond Frostfest where the most popular question concerned the bandwidth of the antenna.

AHVD Winter Wonderland

The Asymmetrical Hatted Vertical Dipole (AHVD) worked quite well for some 10m contacts even with a load of ice on the elements.

HF AHVD on 6m – Practical?

Tall 6m AHVD making local contacts.

Will the KX4O version of the 20-10m Asymmetrical Hatted Vertical Dipole work on 6m? Yes, sort of.

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.
