Hi Carlos,
I've managed to misplace my Mosley book, but here are the specs. on the
TH7DX:
Band: 20m 15m 10m
<2:1VSWR 14.0 - 14.35 21.0 - 21.45 28.0 - 29.7
<1.5:1 VSWR 14.07 - 14.33 21.18 - 21.45 28.6 - 29.6
F to B (dB) 22+/-5 22+/-5 18+/-5
1/2 pwr b.w. 66 deg. 63 deg. 66 deg.
Max gain (dBi) 8.0 8.7 9.6
These data should line up in a 6 x 4 matrix. If they don't, copy the matrix
to a text editor and view it there.
Just for fun, here's the TH5/MK2:
Band: 20m 15m 10m
<2:1VSWR 14.0 - 14.35 21.0 - 21.45 28.0 - 29.7
<1.5:1 VSWR 14.09 - 14.32 21.11 - 21.45 28.25 - 29.15
F to B (dB) 19+/-5 22+/-5 19+/-5
1/2 pwr b.w. 67 deg. 66 deg. 66 deg.
Max gain (dBi) 7.8 8.0 9.0
