Introduzione

Replace the antenna to receive better signal.

    • Be careful when using soldering iron.

    My son snapped off the antenna from our DX-8. Instead of desoldering, I spliced together the core wire from the shortened antenna to a section of one of the interior wires from an old iPhone USB cord and reception is now excellent.

    What should the antenna be replaced with? Is there a specific length and material that should be used?

    I was able to splice it with a short segment of antenna wire from a radio. It works well so far. The wire is similar to the product in the link below. You would cut off a short segment (10”) and reveal the wire and splice it with revealed wire from the antenna. I ran the wire out of the existing antenna hole in the back and taped it the monitor to make pulling it out less likely. The wire I used is stiff so it can be bent to ensure it stands up straight.

    Length of antenna should be 1.2” exactly (but read on re shielded). Reasoning: 1/4 wavelength is ideal reception. 2.4 Ghz actually is 2.4-2.5 approved range from FCC for this unlicensed ISM band. Therefore best to use 2.45 midpoint. 2.45 Ghz full is 122mm or 4.8'“ . 1/4 wavelength is 1.2”. NOTE: what you can see of the antenna on the board and what goes into the antenna housing is actually shielded coax. I image there’s 1.2” of unshielded up in the antenna. So you need to make sure you have only 1.2” of unshielded. I left the coax soldered to the board, snipped to reasonable length, removed shielding, stripped the 24 gauge wire on the inside, measured how much of that was exposed , then cut a length of 24 gauge wire that, when added to what I exposed, would sum to 1.2”. Then stripped that one, soldered them together, tucked that inside, put back together, and tapped the antenna hole closed. Works better than new.

    Finished. I didn’t resolder, I left the original base wire, as many might have noticed, the cable snapped. I spliced it in a half-assed way (later Iif its an issue I’ll go the solder route). for now its spliced with electrical tape just around the connection. I used https://www.amazon.com/gp/product/B0017L... in order to replace the built-in antenna. Getting much better signal strength than original.

That’s fine but what antenna did you purchase? My antennae wire is actually broken, started out with the plastic piece breaking then the cable snapped.

I would also like to know what replacement antenna you used.
