2-Meter FM mountaintopping - cheap and easy


For several years, a great little 3-element beam at KI6SN for 2-meter FM has been used for VHF mountaintopping with great success. Its ease of construction and low cost shouldn't lead you to believe it's not a good performer. Quite the contrary. Nathan Loucks, WBØCMT, described the antenna in a QST piece titled “7 dB for 7 bucks” almost 15 years ago. While 'CMT's RF design is unchanged, several modifications to the antenna's physical design have made this beam an item of ongoing change at KI6SN. The antenna is featured in the QRP column of the August 2007 edition of WorldRadio magazine. For an enlarged view, doubleclick the image.
