Show increasing efficiency of antenna insulator 0 no o matter matte how efficient nn an insulator la Is in dry weather KB its efficiency will always elways materially decrease during rain or snow this la Is particularly th tho case of the common ball type insulator iro for r it a number of 0 years 4 a correspondent spon dent has been using a scheme ie t protect the insulator oh bla ala antenna which las proved prayed extremely efficient this simply consists of covering the 1 7 cily inre tin fin can serves as protector for outdoor aerial insulators insulator Insulat pr with a tin clin can as shown in fhe illustration this can should be of such size that there Is at ai least three of an an inch clearance on either side of f 60 the insulator and it should be placed so sd that the to la at the lower end A hole Is bored through one end of the tin can large enough 4 fo pass nis the insulator eye through and and this hole should aften afterward vard be entirely closed witti solder bolder the can 1 should also be painted inside and out to tg prevent rust and por corrosion roslon this type of covering will keep the insulator fairly dry in the most severe sever e weather and those weak signals will still be picked up tip during heavy rula rain storms ilailo news |
