Response will be less broad since cylindrical nylon chamber should ideally be narrow. The attachment of the coaxial cable to the dipole elements needs some more thought. We did this by simply screwing the coax lead into one of the poles last year, although it would be better to have a more secure joint. Chris is looking into this. George will supply some design specs soon.
Preliminary design is two pieces of sheet metal folded up into two facing cones.
Possible to deploy in dedicated RICE holes. Concerns about asymmetry of azimuthal response - CTA claims we can get around this by properly fastening two together. Off the shelf, ready to go. Too large to be submerged. Not a viable sub-surface design.
