Dualband 17m-20m Moxon
The voltages across the capacitors on 17m are high. At 100W, we're looking at 350V across the 18pF reflector load capacitor and 475V across the 44pF L-network capacitor. At full legal power on 17m, these voltages are about 1400V and 1800V respectively

Homebrew Cobweb or Moxon
Made for 10-15-17 and 20M constructed from 6m Crappie Fishing whips with aluminium bonded to the ends for mounting. These are secured to the base with homebrew 6mm U bolts. The elements are connected to a homebrew 1:1 choke installed in the feeder box
Moxen project
The antenna seems to have a very good front to back ratio, we are using a 88 foot center fed zep as a comparison and after raising the antenna the Moxen beats the zep every time and also hears signals the zep does not
Moxon Antenna Project 17 meter
I use crappie fishing poles, which are 16 foot telescoping fiberglass rods in an X configuration
Moxon for 446mhz
For PMR channels, the results of the calculations are invariant at the mm scale for the 8 channels. In fact, they are identical from 445,927 to 446,115, ie from -0.08 to +0.02 around these
