Description
This design is perfect for matching both long and short length wire antennas for multiband use. When used with the stated lengths shown in the table below, the 9:1 ratio will allow the internal tuner of most rigs to easily match remotely mounted single wire antennas.
For additional versatility, the 4:1 ratio will handle any random, non resonant length of wire which can then be matched using an ATU or many internal tuners. Plus this ratio is commonly used to increase performance of 19, 31 and 43 foot multiband verticals. Unfortunately, both ratios cannot be used simultaneously.
