I have never been a great fan of the RSGB Handbook (usually preferring the ARRL one). However, the latest RSGB Handbook (just published) has been significantly influenced by the success of SOTA. It includes a whole chapter titled “The Great Outdoors” written by Richard G4ERP.
Richard is well known for his SOTA operating and anyone who has met him will have been impressed by his “engineering approach” to SOTA. I saw Richard’s 4 element 2m beam in use last weekend and it is truly a marvelous design. Richard tells me that it is in the Handbook. I suspect that it will be worth looking at for this alone but I am also certain that Richard will have provided much more “food for thought” for the keen activator.
