| Hi all, just found and joined the group. I was wondering if anyone has antenna modeling software and could provide me with the typical radiation patterns for my antenna on different bands. I run a 260 feet (79.268 meters) long doublet antenna about 45 feet (13.71 meters) above the ground and am wondering what the radiation pattern looks like on 160, 80, 40, 30, 20, 17, and 15 meter bands, nulls and lobes? The antenna is fed with about 60 feet (18.29 meters) of 450 ohm ladder line that runs from the antenna feed point to a homebrew 4 to 1 balun and then a short 25 feet (7.62 meters) length of 50 ohm RG8 coax coming into the shack to my Palstar AT1500CV antenna tuner. Any info greatly appreciated. My email address is good on QRZ.com. Thanks in advance and very 73 de KU4GW! |
