- The purpose of a chimney is not to absorb RF radiation but to direct airflow. The only specification that really matters is whether or not it will survive the ambient temperature of its environment.

- Why not do it the way the commercial amp builders do it. Take a piece of about 1/8" silicone rubber sheet, roll it into a tube of the proper size, and use Silastic RTV (TM) or any other RTV) and make

- To expand on this, take a piece of conduit, wood dowel, plastic tube, or anything else of the proper diameter (usually just a little smaller than the OD of the tubes). Wrap the sheet around the tube

- Point taken. With the exception of a chimney pulling double duty as an anode resonator such as in K5GW's 432 amp, the chimney material shouldn't be conductive or rf absorbant. _______________________

- When you need custom silicone parts, such as tube chimneys, they can often be made completely from RTV sealant. Just find or make a suitable form, smear sealant into it, let it set, then remove the f
