I was looking at components on DX Engineering and suddenly their doublet kit popped up. The only gotcha I see is it uses 300 ohm vs 450 ohm, which is probably why it never showed up before. I can't for the life of me find anywhere that explains why you'd use one or the other. I assumed that since the "good stuff" is 600 ohms, the next best must be 450, then 300. But I have no idea. The only thing I can see is the mismatch at the antenna, but you won't know that until you have it up and are trying to use it. Anybody understand this? The new (to me) tuner has a 4:1 balun, but my QRP one does not, if that matters.
At this point I don't even know where I'd set this up. Not being able to just coil up excess coax is a real shift. For the house, 50' of feedline is probably(?) enough. But I may just play around with this at the Super Secret Squirrel Location, or bring it camping, Field Day, or for a longer day in a park where you have to get creative, and more feedline might be better. I don't see getting more than 40-45' up at most.
There's this from DX Engineering. 100' of 300 ohm feedline I could cut to whatever length, assembly required.
