Ok thanks and what is the recommended minimum height in wavelengths the antenna end should to be off the ground if doing an inverted L, sloper, or inverted vee?
That's always a good topic for conversation. Hopefully someone here will post a link to a nice summary of different wire antenna configurations and their patterns. A full answer would fill a text book, but here's my general rules of thumbs.
Lower to the ground = higher takeoff angles. Within 1/4 wavelength of the ground or less gives good NVIS patterns. Higher up gives low takeoffs for Dx. This page shows some nice example radiation patterns for a dipole at various heights.

Inverted-V antennas are also good for Dx with low takeoff angles even when fairly low to the ground.
Inverted-L with good ground radials is similar to a vertical, but with slightly higher takeoff angles. They are strangely omnidirectional.
End fed antennas are particularly hard to accurately model, especially if they aren't half-wave resonant but being forced to look like 50ohms with a tuner. If the wire is truely 1/2 wave long, you can treat it like a normal dipole. It should work about the same. When I use my 63' piece of wire at 21MHz it is 1.5waves long and I have no idea what it's going to do in an inverted-V configuration

.
Frankly, I don't worry about it too much. For portable operations, if I'm trying for Dx I'll try to get the antenna vertical (I've gotten a line over trees 70' tall with my slingshot and fishing reel

). Or maybe drape it over a high branch for an inverted-V. Sometimes I'm lazy and string it horizontally over branches just 10-20' up. Whatever I do, I usually make contacts and have fun.
