Additions:
- SpiderBeam (proposed)
- HexBeam (proposed)
- TH3JR beam (FrankK)
- CalV's beam ant?
- Thunderbird TH3 MK3. The docs that I had were for the TH3 MK4. The measurements are very close. but the beta match is a bit different between the two. The MK3 uses hollow and longer tubes where the MK4 uses solid and shorter rods.
- Gain is 8dB (compared to what, in what condx. prob about 5 dBd)
- GlennT's big beam (Cushcraft A3S? or ??)
- Force12 Sigma 5 (AlanB)
- Vertical Dipole (MikeF)
- VeeBeam (GlennT, MikeF)
- Inverted L (AlanB)
Gain Notes
- use dBi or dBd compared to dipole in same location
