I used a modest (5/8wl 40M) balloon-held vertical around 25 years ago. One trick I used was to tether the balloon from upwind such that with the wind direction those nights the wire was (generally) m

My two C51XRs work great (individually and stacked with the C31XR-H in the middle) but they certainly are big. If you decide to get one I'd be happy to talk prior to your installation. 73, Jim, VE1JF
