I am studying for my general and when I pass I want to put up a HF antenna, my question is whats a good antenna to start with it will be wire. Should I go with a Full size Dipole for each band or a multi band? I have about 130ft of yard from the back of my house to the end of the lot.

A full sized dipole for each band will give you the best efficiency and the widest bandwidth on each band. It is possible to join them at the center and use a single feed line (often called a fan dipole).

You might want to start with a single band dipole in order to gain some inexpensive experience and then add on to it later on.

A great starter antenna--I built one when I passed my Tech+ and bought my first HF rig, many years ago--is a simple double antenna, 33' of wire on each leg, fed with twinlead from a tuner.  Works on all bands 40meters and up, works great, easy and cheap to make!

Good luck and I hope you have fun with HF--it's a great hobby!

First of all, welcome to H.F. - I am sure you will have a great time.

I would also recommend a wire dipole as a good starter antenna - but it is certainly not a compromise.
A wire dipole will give you consistent results with good efficiency.
Once you have grown accustomed to it's performance, you can play with other types for experimentation, if you are that way inclined.
But many guys use dipoles exclusively, and they are proven performers.

Again, welcome and 73

My recommendation is a 100' dipole fed with ladder line to an antenna tuner. The MFJ-901B is a good tuner and is only $100. The dipole or inverted-vee can be at whatever height you can manage. Even 25' is good enough to work DX. 

If you would rather have coax routed into the house a G5RV antenna is good. It too needs a tuner such as the MFJ-901B.

MFJ sells these antennas or you can of course build your own.

How much area do you have and how much money do you want to put into it VS labor?
Are there any restrictions like HOAs or other legal restrictions for antennas?
Are you renting or do you own the property?
Is this something permanent or does it have to be temporary?
 
If you want one antenna that works well with a low angle of radiation,
I would go with a multi-band trap vertical.
However, for it to work well, you need a radial field, the bigger, the better.
You can have it fit inside a sixty foot square and have a very good antenna
system for 80-10 meters.
The radial system is ground mounted, so you don't notice it easily, and the vertical
can be removed in daylight hours if you want to keep a low profile in the
neighborhood.
 
Enjoy the hobby!

You do have a nice yard, a wire antenna would be a great way to start. Do not feel the pressure to jump onto a big tower with a beam, you can be very successful on HF with wire antennas. I too would suggest a fan-dipole and that you build your own.

A good thread on the advantages of a fan dipole can be found at;

Hello congrats on your upgrade, What about a triband trap rotatable horizontally oriented tubular dipole? As you read and learn you will progress and know that the trap rotatable tube dipole offers allot more than affixed wire bidirectional and no control of rotating towards the desired station.

Happens allot.

Rohn push pole rope guys 25ft=30ft up good for 20m 15m 10m.
