Qrp A - 4 Windom Antenna Amateur Radio Ham (7 MHZ / 14 MHZ / 28 MHZ / 50 MHZ)
My English named Windom， Chinese name is transliterated into winton. The earliest record of I， can be traced back to the QST magazine in 1929， Loren g. Windom/W8GZ published stories introduced me， I also hence the name. I am in the thirties of the 20th century， revealed a trend， at the time of my nickname is "single feeder Hertz. Time flies， after years of honing， appear in front of everyone today is a brand new me.Please see the below photos， I am a typical partial feed antenna， feeding point is not like ordinary Dipole antenna in the middle of the vibrator， but in the oscillator total length of about a third of the position. I have 20 miles in length (don\'t want to slanting!) ， the total length and 40 m (7 MHZ) band of Dipole antenna is consistent， but my special is not only can work in 7 MHZ， can still work at 14 MHZ， 28 MHZ， 50 MHZ this three band! This but I\'m willing， because my body strong， got to work efficiency is very high!
