Ferrite rod choke balun

WebHeres a neat 1:1 50 ohm balun for use on HF horizontal wire dipoles. It uses an AM radio ferrite rod, with 3×14 turns of wire. 10-14 turns should be good for 2-30MHz. I used 18SWG enammeled copper wire. It all fits in a … Web1:1 Rod Balun Ferrite Rod: R-61-037-300 Construction: Start by winding a layer of ptfe tape on the rod Cut two 750mm lengths of 1.25mm ecw for a bifilar winding. Starting at the centre of the rod, close wind half the length of the wires towards one end.

A … WebIntroduction. A cost effective current-mode 1:1 balun can be constructed from a length of coax and a rod typically used for a broadcast antenna loop-stick, some electrical tape, cable ties, a length of PVC water-pipe and some connectors. The balun is formed by winding several turns of coax on the ferrite rod.

Web4:1 Rod Balun. Ferrite Rod: R-61-037-300 Use the same winding method and materials as in the rod balun above. Construction: Cut two 750mm lengths of 1.0mm ecw for a bifilar winding. Wind 15 bifilar turns centred and close spaced on the rod. Wind spacing twine between all turns as described above (winding method d). WebHere is a simple idea that is cost effective and simple to make using FB102-31 ferrite beads with RG-58 (1/4″) size cable. Take a FB102-31 bead and insert 4 turns of RG58 spreading them out 360 degrees to minimize the capacity effects. 4 turns give 16X the choking impedance of a single bead.

WebFeb 28, 2024 · This type of choke balun is certainly inexpensive but doesn’t perform consistently over wide frequency ranges or for different coiling techniques. A better technique is to use ferrite for higher resistive impedance over a wider frequency range. Two forms of ferrite choke baluns are popular.
