For a portable antenna I use an EFHW, It is easy to wind a 49:1 UNUN. There are schematics all over the internet I use 14ga fence wire about 64'. Almost every ham band of 40 and higher is acceptable. swr. Signals are strong. You don't need any counterpoise.
Much better antenna for my purposes than any other type of dipole.
