Derek,

The TB3 was the number for a Swan/Hornet 3 el beam. Mosley would be TA-33
and Hy-Gain is TH3 (I have a TH3 MK III). If its a Swan/Hornet the boom to
mast and element to boom are all cast magnesium and one solid piece with
holes for the boom and element. The TB series used
equal 8 foot spacing. The TB2 had an 8 foot boom the TB3 a 16 foot boom
and the TB4 (TB4H)
and earlier TB-1000-4 had a 24 foot boom.
