Only MFJ has exclusive, isolated dipole elements that let you insert balun or coil up coax to isolate feedline. Gives you a true balanced dipole that prevents RF on coax shield, eliminates pattern distortion, reduces noise pickup and RFI radiation from coax and provides deep dipole end-nulls for nulling out interference.
