I just stumbled upon the Temu web site and app. Temu is kind of like a Chinese cross between Amazon and the Dollar Store. They sell telescoping carbon fiber ‘fishing poles’ that look quite similar to the masts sold as ham radio antenna masts. I bought a 32-ft pole for about $35. It took a few weeks to arrive, but its quality and finish are remarkably good for the price. Its weight is only 15 Oz! I just tried it out yesterday supporting one end of a Qrpguys 9:1 UnUn random wire. Worked like a charm. I have no idea yet as to its durability. I bought a wire coil-on-stake fishing rod holder from Amazon as a ground mount- worked perfectly.
Bottom line: a 15oz 32’ telescoping mast and mount for around 40 bucks seems like a good deal. Stay tuned and I’ll let you know if/when it fails.
