Its fed with standard 50 ohm coaxial cable, through the center associated with the dipole using center conductor attaching to at least one side of the dipole and shield associated with the coax to the other side. The type of coax is your decision however the larger coax like RG8 will give a little less reduction dependent on feedline length. The coax should come out of the dipole at a 90 degree angle towards line preferably when tuning plus the last set up.
No matter which part is linked during the coax equally lengthy as neither region of the antenna is shorted to the other part, ergo, the insulator in the centre. Seal all connections on coax end in which it links towards the antenna including the end regarding the coax. This keep water out.
From antenna, the coax should go to an environment wound choke at antenna as previously mentioned above making use of the same coax that could go right to the transmitter.
NOTE: instead of have connections at each and every end for the environment choke, just make the feed range coax about 18 to 21 foot more than needed seriously to attain from the transmitter towards the antenna and then breeze your coil on kind and affix to the antenna.
