"Jimmy" wrote in message . com... In the plan I have for one it calls for a piece of fiberglass rod, others bakelite. to keep the two sections of the J at the right sepration. Are we talking regular J, or Super J here? The antenna you're describing is a Super, a colinear array with the middle phasing section. In a normal J-pole, there is no insulator needed. Here's a confusing point from the original post... I recently built a two meter j-pole.In the plan,I saw no mention of pvc use.Yet,I had to place a piece of pvc between the two uprights to get the swr to fall.Is there something I missed? / Is the pipe used in an insulator fashion, or is it used to spread the Q-section? I believe it's the latter... if so, the newbie can just bend or re-solder the pole so the spacing's correct. And if the newbie is describing a 300ohm twinlead J-pole, then I give up. Somtimes mechanical rigidity is enough, for one like the latter search for "copper cactus". A thing of beauty... I've got a nice copper J for six that I'm considering converting to the saguaro configuration. __ Steve KI5YG .. |
