If it Is not built properly It will allow energy to leak i-way, and will be inefficient in bringing in distant stations. In general, each set ot plates should be well insulated, preferably with bakellte, from each other and from all neighboring conductors. A yearago it was difficult to find condensers which employed a "pigtail," or flexible connection, for the movable plates.

Without such connection, the friction bearing must provide contact, and It is Inefficient when worn or dusty. MAKE SPECIAL DIALS. Dials are made to give a vernier action on any condenser.
