 +===== How do I put up this antenna? =====
 +
 +This is a very flexible antenna and it doesn't even require a counterpoise. Just ground it and you're good.
 +
 +Here are some examples:
 +  * FullyHorizontal 
 +  * Inverted L configuration - Have a part of the antenna vertical and the rest horizontal. Keep the vertical part away from the house as it can pick up a lot of noise. 
 +  * Inverted V - No less than a 120-degree angle
 +  * Fully vertical
 +
 +I have heard stories of bends, weaves, and other not-so-common configurations and it works for them. It can be used for portable or permanent. It's a really good all-around antenna.
