Repost: Introducing an antenna called “Long Tall Sally”

Way back in February 2024 Ham Radio Outside the Box published a post titled "A Most Unusual Vertical Antenna for 20m". It introduced the idea that the radiating element of a raised quarter wave vertical antenna could be stretched to a much longer length with a corresponding shortening of its radials. The idea is worth … Continue reading Repost: Introducing an antenna called “Long Tall Sally” →

TechTip #3 Improving the “Titanic” 40m field expedient backpack portable antenna

TechTips on Ham Radio Outside the Box are brief posts of a technical nature. Back in October 2024 Ham Radio Outside the Box introduced an interesting design for a compact, field portable antenna for the 40m band. Named the "Titanic", it was a T-antenna similar in appearance to the one used on the tragically famous … Continue reading TechTip #3 Improving the “Titanic” 40m field expedient backpack portable antenna →

No loading coils, no top-hats, no transformers, no ununs, no baluns, no tuners, no radials – just the perfect antenna?

Just imagine, if you could get rid of all those lossy loading coils, impedance transformers, ununs, baluns, tuners and ground radial trip wires. What do you have left? Could it be the most perfect, the ultimate, 100% efficient, dream antenna? Yes, yes; it's a dream! But back in the real world ... I spent most … Continue reading No loading coils, no top-hats, no transformers, no ununs, no baluns, no tuners, no radials – just the perfect antenna? →

There is a “small” problem with the QRP Labs QMX transceiver – and an easy fix

Why was it born so beautiful, why was it born so small? I have to admit to a love/hate relationship with my microscopic, yet bursting with features, QMX transceiver. This marvel of technology is densely packed into a shirt pocket-sized sturdy aluminum case. Just how did the R&D department at Turkey's QRP Labs manage to … Continue reading There is a “small” problem with the QRP Labs QMX transceiver – and an easy fix →

An Outside the Box look at the 48 inch base loaded vertical antenna

It's not the smartest idea really is it? A quarter wavelength vertical whip for the 20 meter band should be around 5 meters (17ft) tall. Why build a vertically challenged whip that is less than a sixteenth of a wavelength long and expect it to work? And ... with a QRP transceiver too! Yes, indeed … Continue reading An Outside the Box look at the 48 inch base loaded vertical antenna →

A 5-Band, Lazy-L, Linear-Loaded, Ladder Line Antenna (aka the “5B6L”)

About a year ago I mentioned an antenna devised by Peter Waters G3OJV that used a 13 feet (4 m) vertical wire to create a multiband antenna. I used Peter's idea to create "A Simple, Low Profile, Multiband Antenna for POTA". The antenna was designed to work on 20m, 17m, 15m, 12m and 10m with … Continue reading A 5-Band, Lazy-L, Linear-Loaded, Ladder Line Antenna (aka the “5B6L”) →
