BNTECHGO 20 Gauge Silicone Wire Spool 100ft Ultra Flexible High Temp 200 Deg C 600V 20 AWG Silicone Wire 100 Strands Of Tinned Copper Wire Red And Black Each 50ft 2 Separate Wires Stranded Wire

Good stuff, has good insulation, and the wire is flexible, I use it for radials for a HAM radio antenna.

I’ve been using this Portable 80m–10m No‑Tune End Fed Half‑Wave (EFHW) Antenna with my Yaesu and other HF gear, and it’s been excellent for both portable ops and backyard setups. The “no tune” aspect is real — I can put the antenna up quickly, and it works across 80 m through 10 m without constantly firing up an antenna tuner. That alone makes it a huge timesaver when I’m on the go or setting up at field locations. Installation is simple: toss the end high in a tree or onto an elevated support, run the feedline back to the radio, and you’re good. The built‑in matching transformer does its job well — SWR stays low across most bands (well within usable ranges), and I get solid contacts into DX stations with moderate power. Signals come in clear, and I’m not fighting a high SWR or wasted power. Pros: ✅ Real “no‑tune” multi‑band performance (80m–10m) ✅ Quick and easy to deploy in the field or backyard ✅ Matches well with typical HF rigs (FTX‑1, Yaesu, etc.) ✅ Good efficiency and solid on‑air results ✅ Ideal for portable, camping, or emergency use Cons: ⚠️ Requires a decent support height for best performance on 80 m ⚠️ Balancing and feedline routing still matter (like any wire antenna) Overall, this is a versatile and reliable EFHW antenna that saves tons of setup time while still delivering excellent on‑air performance. Whether you’re doing portable field ops, contests, or simple backyard HF fun, it’s a great all‑around antenna.

If you are looking for wire that is extremely flexible, then this is the stuff for you! I used it to reach a couple aftermarket sensors on my boat's outboard motor. Obviously the engine moves around a lot, so flexibility was very important. And the silicone insulation is good near the other hot components, although I did put it in a flexible protective conduit. A couple months later it is showing no wear, so I would rate the quality high, and a good value for the money.

柔らかい質感で加工作業も非常にやりやすかった。

Very flexible, I used it to build a cobweb antenna for use with my Ham radio. Each strand is tinned, which is bonus ofr outdoor use.
