Collinear Delta Loop

I'm a huge fan of delta loops.  They have, in their various guises, made it around the world with me over the years.

Sometimes, I add a longer, reflector loop for certain paths, typically into Africa, which is never an easy direction from here.  But it's a bit of a pain to arrange, and spacing tends to vary wildly if the winds are up.

So, a different way to get about 4-5dBi total gain is to connect another, identical loop to the feedpoint, and run both as a collinear array.  By way of comparison, this the same gain you would get with a hexbeam antenna, but that would need to be some way up in the air for best effect.

For an extra 'S' point of gain, just run two loops from the same feedpoint.  Easy!

Result?  The deltas can flop about relative to one another as much as they like, it makes no odds.  The matching is only marginally affected, and signals take the predicted 'S' point leap upwards.  What's more, it's dead easy to run up the extra delta on a fishing pole, and then bring it down again if there is no real need for it, or the neighbours are PITAs!

So, hexbeam-like performance for the price of two fishing poles and some wire.  That's cheap hamming!
