A Co-ax Trap Dipole For 40, 30 and 20 Meters or at last that was the intention

The Double Bazooka Dipole is a very efficient single band antenna which is very quite,and does not require the use of a balun. This antenna consists of coax (RG58) with the shield split at the center and the feedline attached to the open ends.

A dipole antenna for 7 MHz support for this antenna is fiberglass military mast

The gamma match was originally invented as a means of feeding vertical monopole antennas for medium wave broadcasts, which were earthed at the base for lightning protection- Hams are more likely to use a gamma match to feed a dipole or loop element, but the basic theory is easier to understand for the case of a quarter wave monopole.
