6cm slot antenna 20 slots 14.7 dbi
I make slot antennas for all frequencies from 23cm to 24ghz and all frequencies in between hams bands
24 GHz Omni antenna designed
Some points about 2.4Ghz coaxial cable antenna for routers and Robotics Vehicles: Radio equipment using the license-free 2.4-GHz ISM
Alford-Slot Antenna
5.6dBd gain flat VSWR and good gain bandwidth performance over the entire 420-440 MHz band
Antenna a barattolo
E' possibile utilizzare barattoli di provenienza alimentare con diametri compresi fra 75 mm e 85 mm, misure che garantiscono il massimo rendimento nella zona dei 2.4 GHz

23cm Yagi Antenna building Finished antenna at 1275 MHz SWR under 1:1.5 at resonant frequency
50 MHz preamp Gain 26dB with the BFG135 Preamps for 144 and 430 MHz, for 50 MHz, the BFG135a is a cheap transistor and in my view rather strong. It is not easily damaged by static discharge or RF power. FG connection
30 Volt Computer Power Supply Stack A bonus was that i discovered that these did not need a standby load connected to the supply to keep them running just apply mains power and close the Start lead to ground
