Anyone wanting to load into a tower with some kind of HF antenna on top might
want to consider creating a loaded, folded cage monopole like the Collins
237W-1X. (For a picture of one see k0hgw's listing on QRZ.com) This
configuration permits the tower to be grounded at the base and provides a very
wide bandwidth while the HF antenna acts as the top hat. The length of the
cage elements are very uncritical and matching it with a simple L-network is a
piece of cake.
