W3DZZ Multi-Band Dipole Antenna - Let's Build One

The W3DZZ Antenna is one of the classic ham radio HF antennas. It was conceived and designed around the same time as the famous G5RV antenna. Different concepts but similar results. Here Peter G3OJV, describes the antenna for ham radio operators. He also gives information on another, less well known, half size version.

Hi Peter,
I always enjoy your videos, good straight-up advice.
And there is no yelling or annoying music in the background. 😃

It is a rare business owner who doesn't just try to sell us the most expensive thing. Thank you so much for the honest advice you put out and how we can manage the hobby even when on a budget.

Well done Peter. Thank you for reminding us that SWR isn't everything. I believe we hams fixate far too much on SWR when we really should be looking at field strength.

I believe I have a new antenna project coming up, at least I know what the type/name is: W3DZZ.
I like the fact that Peter is focused on post apocalypse HF antenna building, based on his half century of Ham experience and a great antenna design from the 50’s…that still gets it all done. He can probably build a properly tuned antenna without anything beyond a tape measure. Nice way to learn.
Keep up the good work Peter!

Well done on your 52 nd year in business, I picked up a FT710 from the shop in late September

well done peter on 52 years. keep enjoying the radio. 73 m0fsd

Thank you Peter for all your videos and advise. Much appreciated!!

[wildbill]

Great video, very well detailed explanation thanks Peter!

[BartVanAllen]

I understand the "English" system of measure - I know how long my foot it, I know how far it is from my nose to the tips of my fingers, I know the length of how far I walk at a normal pace in 15 minutes - I do not naturally understand the fraction of the earths circumference or whatever that basis of the new age measure is.
Keep on using natural measures, you are doing fine.
Great vid, always look forward to your casual and competent presentations.

more hints and tips . keep them coming . had a go at some traps a mag loop . love the loop . collecting old cb radio antennas at the min want the alloy . 10 15 and 20 my next goal vertical . no garden is my problem

Peter, thank you very much for using feet!

You might find this interesting. In the in the US Marine Antenna Handbook. MCRP 6-22D "To make a long wire antenna directional, place a terminating device
at the distant station end of the antenna. The terminating device
should be a 600-ohm" "Constructing a long wire antenna requires only wire, support poles,
insulators, and a terminating resistor (if directionality is desired).
The only requirement is that the antenna be strung in as straight a
line as the situation permits. The antenna is only 15 to 20 feet above
ground, so tall support structures are not required. The antenna is
normally fed through a coupler that can match the antenna’s 600-
ohm impedance. Coaxial cable can be used if a 12 to 1 balun is
available to convert the coaxial cable 50-ohm impedance to the
required 600 ohms." Why not use a 9:1 and a 450ohm 200w resistor terminated to ground?

Very interesting video, my Danish friend has used one for years with much success.

Well done Peter. You might want to try out the coffee and ham radio ARES end fed antenna. I built it for my QRP rig and it has amazed me with it's swr across many bands.

Another great video, many thanks! Robert K5TPC

[dandypoint]

It seemed like everyone I knew had a trap dipole in the 60’s!

Another option for a small garden is to use one leg as an inverted L, tuned against ground with a few radials.

Hi Peter. I wonder why you didn't talk about making the whole trap from one lenght of Coax. Then you dont have to search for the right wire, coilform and inductance, nor searching the hamfests for highvoltage capacitors. OK, it is a bit difficult to explain in some minutes, but you find it in "Rothammel's Antennenbuch" or in "ARRL Antenna book" im shure also in RSGB publications. And for QRP antennas it works fine and lightweight with the Red Amidon #2 Mix tores and normal capacitors.

[jimfuller]

The W3DZZ was my first antenna. I recall feeding it with 75 ohm twin (can you still buy that?). By joining the two feeder wires together before the ATU it would even work on 160 M, like a Marconi T.

[vetinger]

To mush talking, and there will be good give more details of these antennas to be able to make them. Will they work in attic location? Thank you anyway! 73!!!
