Widebander mk3 QRP Ham Radio Antenna for Amateur Radio

Following the success of the Mark II, the quest for greater efficiency has led us to replace the whip with a stealth dual wire kit. 

Wonder LOOP WL 750

Utilising our unique “HLT” Hybrid Loop Technology to cover 7 – 50 MHz in one convenient package by employing two loop circuits with a common feedpoint.

Tuneable counterpoise

The Tuneable Counter Poise plugs directly into the MK 3 above or can be attached to a rig chassis if a wire antenna is being used. The counterpoise greatly enhances the efficiency of the Widebander

Widebander mk3 BNC

The standard MkIII comprises the usual BNC and wire adapter so you can connect your own whip antenna or use a long wire and counterpoise

RWT-166 160m – 6m

The RWT-166 covers 160 – 6m as the name suggests and uses a stepped inductor and a variable capacitor as an LC match for a wire antenna.

About the founder of Wonderwand

Carl, G0NZI

The Wonderwand came about because Carl saw the need for a compact portable antenna to cover the HF bands. This ruled out the convenience of full sized antennas. 

Hence began the quest for the ultimate QRP Antenna! The modern Widebander is available for Yaesu and Icom transceivers and is compatible with many others such as Elecraft . For enhanced efficiency a long wire and counterpoise is a must. The easy to carry space saving whip configurations grants ultimate flexibility.

The best antenna is the one you have with you

Ah, SOTA! It’s more than just an acronym, it’s a sunrise symphony echoing from a mountaintop, a picnic of triumph amidst windswept crags, a whispered conversation across continents woven on sunspots. The joys of SOTA unfold like a crisp map on dawn-kissed stone. First, the ascent. […]

Dont’t take our word for it – here’s what our clients say:

Thought I’d let you know that I took your suggestion of the W3EDP and connected up an 84ft wire using the tuneable counterpoise and immediately I noticed a real difference in receive. On 160m I thought I’d try my luck and made two contacts with reports of 5/8 into South West Scotland and 4/4 into Rotterdam on 5W!! The wire is configured in my 40ft garden highest point 17ft down to the bottom of garden and around garden at 6ft👍

Thank you again I’m even more of a promoter of Wonder Wand now 🙂 Keep up the good work.

Good antenna!

It is not the same as a 4 element yagi up in the air 100 feet. But it is not supposed to be that. This antenna IS better than any other portable “mounted directly to the radio” antenna that I have ever used.

Good stuff! Thanks!

Despite the awful conditions over the weekend I still managed several reasonable contacts into Europe, the best being Portugal and Slovakia using the Wonder Loop and the Mk4, I just missed a Sicily contact on 6M as the band went flat, on Saturday I made several 6m contacts on the loop while the conditions were ok – 5/1 & 5/2 received on most qso’s but I was easily heard with 5W on the 817, most of my contacts were very complimentary regarding the audio quality so overall I am very pleased with the loop, hopefully the conditions will improve in the next few days.
