Hi Folks - smtp send sever down - on web mail. TKS Tom, N4KG, for sharing the # of radials vs length of radials for verticals. Longer the length of radials, more radials you need (for ground mounts). Think of of it as your "overall artifical ground density". 4/10 wavelength (at lowest operating frequency) is a good number for the length of radials for ground mounts. That's why all my radials for my 20 thru 10M H.B. were 25 ft. For radials of that length, I needed 36 radials for Tom's Rule !!!
Not feeling well today so not really made up my mind, but to keep it simple, think I am prob going to go with either a Hustler/BTV or Hy-Gain/AVQ elevated mount and elevated tuned radials. Yeah, I know traps a bit lossy and not perfectly hermeticly sealed. For about $ 120.00 for the Hustler 4BTV, and the good reveiws on E.Ham Net, seems like a good choice for a "bought vertical". Not really worked many "new ones" on 17 or 12M anyway, and Hustler does offer a 30M "add-on kit" Your comments very much appreciated. Some of you were using a length of wire (66/132 ft) thrown over a tree limb in "Inv Vee" config and feeding one end with coax and a number of tuned/untuned radials connected to coax braid at feedpoint. You can most definetety tune "this snake" for a 1:1 SWR with your "T" tuner, but try putting a SWR Meter in-line with coax between tuner and Ant and see what the real SWR is on the coax. Bet it is 3:1 or higher !! So if you running relatively high power, count on some significant dielectric losses in your coax, and mabe a coax short to to occur if the VSWR at a voltage loop exceeds the diectric breakdown voltage of your coax. Again, thanks all for the input !!! 73, Larry Subscribe/unsubscribe, feedback, FAQ, problems http://njdxa.org/dx-chat To post a message, DX related items only, [EMAIL PROTECTED] This is the DX-CHAT reflector sponsored by the NJDXA http://njdxa.org
