No thanks. I work as a tech in the community FM broadcast industry, and that is what we use in the 88-108 MHz band.......1/2 inch hardline with N connectors.Maybe many of you should consider the same with your base antenna?
On 11 meters I run good 'ole Belden 9913 RG-8 with 239/259 connectors.
Unless you are running hundreds of feet of line, there is absolutely nothing to be gained by running expensive hardline on 11 meters. Sure, the hardline has less loss per 100', but it's absolutely not enough to make any difference whatsoever in either receive or transmit !
The only reason to run hardline is if you are operating at 50 MHz and above, where line loss is much greater than it is at 27MHz. Or you are running a LOT of power.....like more than a couple thousand watts.
For 11 meters, hardline is ridiculous overkill. If it makes you feel good do it by all means, but unless your rig is hundreds of feet from your antenna, you are gaining nothing other than that good feeling LOL!
