Hello to the group, I have just joined the group.The local radio club that i'm in it putting together a cavity duplexer alot like the one in the july 1972 issue of qst.We are going ahead leaps and bounds but we have came across a problem it is suggested that we use rg55/u coax on the cavity's but the problem is that i can't find anyone in australia selling that type of coax.So is there anyone that could help me in suggesting what else could be used.I have found a couple of sites on the net that have rg55/u but in roll form.We are looking for around 2 metres of it only.
Any help would be most great Thamks Wayne vk4cya
