Yagi for Channel 4?
Ive been lurking for a while on this forum and reading a lot ,understanding some and ceartainly learning a lot. An empty vessel is easy to fill and all that.
My specific problem is that the channel I really want is cbc on channel 4 ,60 miles away(70mhz if I have it right) .Hockey ,you know. Using k7mem's quick calculator I found I would have to have a boom length of something like 24 feet.Now I could mount that along the ridge of the house , only it runs the wrong direction! The calculator kept admonishing me that too short a boom would not give a high enough gain. That discouraged me. Now I see the elegant work posted by Mlord and Im inspired to try some thing. . Im wondering if I might get ok results with what looks to me to be compromise designs posted in other threads by the meteor watchers.(sky scan scienc awareness project)with boom lengths of .45 or .65 the wave length.(4.28m).Im also wondering if 1/2 in cu pipe from the scrap yard would work using the common sweat solder fittings or is it too big in diameter
