This is a case for an FT-240-size based impedance transformer or RF choke. The hole is 65mm so a very tight fit. I suggest using 1mm diameter wire, otherwise an FT-240-43 will not fit. The FT-240-61 I tried is a tad smaller, but still a tight fit, and not for the same frequencies. The connector hole is for a BNC. At the other end there is a 3mm hole you can drill out if needed for a ring connector, bolt, nut and butterfly nut for your half-wave antenna wire. I have plenty of videos on how to make these antennas on my Radio Prepper YouTube channel.
