• PA0RDT MiniWhip - When experimenting with the WellGood Loop antenna, I came across the PA0RDT MiniWhip design referenced in several places. The construction of the PA0RDT MiniWhip is simpler than the WellGood Loop since there are no inductors to wind, but during my testing, I have found the loop to have slightly better performance.

• The Antenna Torque Calculator - This unique online tool helps Ham Radio operators to choose the right rotator for medium and large HF antenna systems. The algorithm implemented in this calculator is the result of 40 years of experience in the HF Antenna sector. Given the Wind Speed, the total antenna square area, and the boom length, it will return the calculated torque value.
