Ladder line should be kept away from metal objects. Many people avoid using ladder line because they feel they can't bring it into the shack. I have never had issues running ladder line right into my shack. I've always fed it through a window but I've read many alternate methods for those who don't have a window close. Ham Radio is all about experimenting. Just try it.
Another point not to overlook. I use a 160 meter full wave loop fed with my home brew ladder line. I use this antenna on all bands with excellent results. Using ladder line for multiband operation is an excellent choice over coaxial cable for many reasons which I won't get into here. BUT...... WARNING... For multiband HF use, it is best to avoid certain lengths for your ladder line. This website does a nice job of explaining do's and don'ts. Click the botton for further details.
Here are links to 3 short videos made by my friend Randy KB2ZVP which provide an excellent overview of the process.
