Moxon Antenna for LRS TX
This is first Moxon antenna I made. It looks like having 5db more gain then RMILEC SRC771 1/2 Wave Length Antenna (according my simple measurements).
As always my RF generator’s used to drive TX antenna, and Immersion RC power meter, connected to dipole antenna to measure signal level.
RMILEC SRC771 generates -28,03 dBm
And moxon antenna…
Generates -23 dBm
So it seems to be better, but i wonder if gain shouldn’t be grater.
Using directional coupler i found out that lowest SWR is for 420 Mhz, but i’m not sure how to tune it…
An antenna looks like following.
