Topband: Toploaded vertical - SWR

[Joe Subich, W4TV]

1) move then ends of the top loading wires further out (flatter)
2) use a 4:1 auto-transformer at the feed point - your antenna
    analyzer says the real impedance is about 15 Ohms.  A 4:1
    auto-transformer will get the SWR down to about 1.2:1.
