It is also possible to add a much longer whip in addition to the extra<br />

antenna accessory arm. The configuration below uses the 12 foot shockcord<br />

whip instead of the 9.5' whip. With the longer whip two more taps<br />

resistance has risen to the point where the TRSB must only be set to 2:1.<br />
