Yes Yes Good Good i like idea very much of you send me free antenna to use my house. Free antenna cheaper than build or buy. This great site free stuff for christmas many thanks 
A wire dipole is one of my favorite antennas.

Used to make the on on the Left, Picked up a telescopic mast from RS a Mirror mounth and 102" stainless whip. Had a 1:1 all 40 channels. Yes there are better antennas but at the time I was on a budget and it worked very well.
One time I used one of those paint / mud / mini-concrete mixers you'd affix to the end of a drill. Basically, I shoved the part you'd put in the drill into the ground, and made a balancing act out of a mounting bracket and coiled 11m radio antenna as a base station. The only factor that matters here is how large the mounting bracket is compared to the mixer since...you know...gravity. A 33 degree angle about foot above the ground seems to work best.
You can lower the SWR by using a piece of speaker wire (or any wire, we're improvising here people), stripping it and wrapping one end between the antenna and mounting stud itself, then taking a piece of copper rod and "grounding" said speaker wire - take extra care in making sure the speaker wire does NOT touch the mixer and "floats" above your paint mixer mast. This actually works btw, it's hilarious.
You could use a full 102" whip if you want and achieve the exact same effect but the usual cheap roadpro or firestik stuff you can find at any truckstop works surprisingly well. I went through a phase where I'd test stuff out using this setup before I put it on my truck. Keep reading since theres an obvious flaw...
Heres the kicker: there is no ground plane to speak of which means the signal is sent straight up into the air due to the EXTREME low angle. I mean this very literally, the ground should be about a foot below the antenna, max.
I made this as a joke but it turned out to be a legit DX experiment. Enjoy.

This is my favorite WWDX offering. 
I put this together in about 4 hours because I wanted to see what results could be had from such a thing. First time up the SWR on 40 is 1.4:1 and on ch1 it is 1.9:1. Talked and receives just fine. More later. Gotta go back to work.
All the weird curves is my camera doing strange things again? ? ?

@HomerBB is the king when it comes to building antenna projects with parts from home depot and tractor supply hardware.

(I still think the chicken wire antenna was the winner)
Building a working 11m antenna can be done in minutes.
Example:
One (1) 9' household extension cord.
One (1) coax long enough to get back to the radio.
Cut the female block off the cord, split the two wires apart from each other, and attach one end of the coax to the male plug prongs.
The 9' cord is now ~18' long. Fold back ends equally to tune it. Your new dipole can be hung vertically, horizontally or as an inverted Vee.
Not the only quick, easy, and cheap antenna option, but an example of the not so complicated manner of many antennas.
