Dielectric's expertise in the TV and FM fields extends to our RF Systems. I've dealt with SCIF penetrations at a number a gov't facilities in Hawaii. If you need to go bigger than that, you'll need to utilize a "flange isolation kit", which provides separating/insulating plastic/rubber gaskets and bolt shields that prevent metal to metal contact at the flange. The permittivity of an ideal dielectric is independent of the magnitude of an applied electric field; the material is said to be "linear." 1 However, all practical dielectrics fail in this respect with sufficiently strong electric field. Other back up security systems such as cyphers, closed circuit television, and proximity entry cards or fascards, and personnel detection and intrusion devices should also be evaluated, analyzed and effectiveness comparisons made. When a dielectric is subjected to an electric field, there is a limit to the field up to which it acts as a perfect insulator .beyond a If the length of metal conduit entering the facility prior to transitioning to the PVC break is as long or longer than the wavelengths we are interested in picking up, then we will have an unimpeded pick up and reception of that wavelength and frequency.
