DX Engineering supports AHVD antenna
DX Engineering supports the build of the Asymmetrical Hatted Vertical Dipole (AHVD) antenna with standard and two custom parts.
AHVD
History, theory and build instructions detailing this option for a freestanding portable vertical antenna for the 20-10m bands.
Berryville 2015
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
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
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
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?
Will the KX4O version of the 20-10m Asymmetrical Hatted Vertical Dipole work on 6m? Yes, sort of.
This Balun Chokes
Jim (K9YC) Brown’s toroid winding recipes provide a superb RF choke balun for 30-10m using RG316 and a #43 toroid.
Hatteras Ham Shack
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.
Vertical Dipole at Lighthouse
The asymmetrical hatted vertical dipole (AHVD) provides a quick setup HF antenna at Hatteras lighthouse.
Build this Vertical Portable HF Antenna
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
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.
