And the previous scores substantiate such. I've been using a 134 ft center fed dipole with balanced feed for 50+ years at my various QTH's. I've yet to find any antenna that performs better and always consistently without effects of wind, rain, snow and ice. 73 Bob, K4TAX On 6/14/2019 6:47 PM, AB4IQ wrote: > We use Ladder line fed dipoles.
