So a friend of mine wanted to get on 10m and was looking for an antenna, so I looked in my junk box to see what I had
-5 foot section of 3/4" galvanized EMT conduit
-one, A99 radial
-and a99 3/8-24 fitting
-ratshack plastic project box,
-some scrap PVC
-so-239
-some braided copper ground straps
well put everything together and added 4 wire radials, they where a bi long, about 9 foot, they are tied into a tree at ABOUT 45 degrees, plus or minus a bit, either way sloped pretty well
the emt is at the base, the A99 radial is on top of the EMT and cut to correct length and the center of he coax goes to it, the coax shield goes to the radials and every thing is isolated from the mast by the PVC
when checked at the feed point with a MFJ-259 it shows the resonant point to be around 28.4Mhz 52ohm, 1 Reactance, 1.0SWR
it shows a 2.0 swr at around 26.5 Mhz and 31.5Mhz.. How is this even possible? is it possible that my friend misread the meter?
