I agree the HOFI HOSCHA remote switch is great.  We sold a dozen back in the
early and mid 1990's at Electronic Switch.  Mr. HOFI is hard to deal with so
you must get them direct.  He did have a web page that also includes the
remains of the Fritzel antennas.   HOFI also makes excellent 5 position
manual coax switches (I have the PL259 and N versions).  There is NO
crosstalk with them as there is with the cheaper alpha delta and the like
switches!  However
buying a switch with lightening protection is a metter what is
advertised its cannot be done!!!!
