Here are some comments and suggestions from Linas: This is one more video about the minimalist radio set-ups. This time I took a chance of a nice autumn weather and drove around my native town of Vilnius carrying along probably the best QRP go-box I ever had: the KX2 all-in-one radio and the no-cost, zero-waste mobile whip. I was looking for an answer on how effective could this radio be operating in a noisy and constantly changing mobile environment, running 5W only from its internal battery pack and, even more interesting part, could I be heard radiating with the 122 cm long mobile whip mag-mounted on the roof of my car!

Here are some comments from "Red Summit RF": I take you through my steps to build this 20 meter-30 meter-40 meter linked dipole antenna, including construction of the insulators, and a trip into the back yard to tune it up.

This is a great antenna to use for portable ops like Summits on the Air, Parks on the Air, or similar events. They perform quite well. The one I constructed only weighs 8 oz. It is best suited for QRP. I'm not sure how well it would perform above 20 watts
