A pcb for a 100W Fnd Fed Half Wave Antennas (EFHW) for SOTA, POTA,... xOTA
Based on my xOTA-Antenna Design (https://github.com/DG1JAN/xOTA-Antenna) I made an updated Version with a better Toroid for higher power (100W SSB) and lowe core losses.
1x PCB: custom order with Gerber Files from PCB manufacturer e.g. from https://www.jlcpcb.com
1x Toroid - FairRite 2643101902 (DigiKey is a good source)
1.6m of Trafo wire - e.g. BLOCK CUL 1mm
1x BNC Socket -e.g- Amphenol B6252H7 / Telegärtner J01001A0038 (or similar)
1x Plastic Wedge (3D Print Part, STL is in the Repo,use PETG) https://github.com/DG1JAN/xOTA-Antenna-100W/blob/main/xOTA_100W_Wedge_DG1JAN.stl
1x Cable Tie 2.5mm wide, 150cm long
1x 100pF Ceramic Capaciator - e.g. TDK CC45SL3FD101JYVNA (DigiKey is a good source)
2x 4mm Banana Socket* - e.g. GTIWUNG 4mm Plug from Amazon
9cm Shrink tube - 85mm wide
optional:
1x S-Hook Carabiner for wire straun relief and easy mountung
1x 3D-Printed Coil Holder ( a small coil of 10Windings ~1m from the UnUn in the Antenna Wire results in a better match of 40 & 20m Band) https://github.com/DG1JAN/xOTA-Antenna-100W/blob/main/xOTA_100W_Wedge_DG1JAN.stl
*alternativ mountting Option for Antenna Wire (2x 4mm Banana Sockets are not requierd):
- use M3 Screw and Wing nut
- solder Wire directly
