The classic feed is the quarter wave stub, in the VHF world it is called a "J pole". You tap up on the stub to get the 50 ohm point above a short on the stub.

In horizontal doublets, such an end fed half wave is caled a "Zepp" short for Zeppelin antenna, which used a HF "J pole" feed.

The practical end impedance of a half wave of wire is not infinity as the zero current might indicate. Instead with the insulator effects,capacitance to earth etc, you will do fine to assume it is 3000 ohms.

Then go to a Handbook and find the reactance charts and see for the band frequency you want what size inductor has reactance of 3000 ohms. Tap antenna to one end ground other end of such an inductor. Either wind on two turns insulated link coil on lower end near ground, or tap up from ground until you get a good match to coax. There you have an end fed half wave wire. For a horizontal antenna, of course the Zepp feed is more practical, but limits the antenna to what bands it will operate. A tuner and balun is able to extend that, in that case, connect the balun where the coax would have gone, or try end feeding the stub to the balun. A true balanced antenna matching circuit is better to avoid any frequency effects of the balun having a tough match.
