Hello The Net:
WA5VJB is offering a Vivaldi type pcb printed antenna, linear
polarization, for 5.1 thru 20 GHz.
with useable gain 2-25 GHz, price or 5$ each. It is not yet on his
Michelle, I believe you have this version in hand.
Kent is also considering a newer design Vivaldi type with a 3 octave
matching network to cover down
below 3.4 GHz, where we will need it.
For tripod materials I prefer the mil surplus "MS-44" masting used as
the 3 legs
with a tripod adapter "AB-1089/U". Easily to put together or knocked down.
Legs can be in increments of 5'. For semi permanent installations I
prefer to bolt parts together
and to add a horizontal brace of 1-3/8" OD galvi fence rail, about 18"
from the bottom.
The masting is 1.625" OD, 1/8" wall aluminum and easy to machine.
Each section is about 66" long with 6" necked down to fit the next section.
