100-Ft. 300-Ohm Flat Twin-Lead Cable

Comments about RadioShack 100-Ft. 300-Ohm Flat Twin-Lead Cable:

I've been using this stuff for years for HF antenna's. It's durable and easy to work with. It demonstrates minimal feedline loss compared to RG-x.

THe people that claim its too thin to strip--you're morons and should go back to 11 meters.

This is great quality 300-ohm twinlead, the best I know of. I use it for an all-band center-fed Zepp. Latest antenna has been up for several years. Copper wire is durable, easy to solder, unlike the cheap copper-plated steel wire found in other brands. Quality insulation. Buy some for a spare - it won't be available forever!

Comments about RadioShack 100-Ft. 300-Ohm Flat Twin-Lead Cable:

This line has a pair of nominal 22G conductors made with 7 strands of nominal 30G copper wire. Nominal thickness of the flat line is 0.125 inch and nominal width of the line is 0.408 inch. It is packaged in a manner that enables complete examination and measurement at the store.
Currently in use as feedline for HF wire antenna systems operating between 500 KHz and 30 MHz.

If they are afraid to tell you the conductor size, you probably don't want to buy it.

Ham radio feedline. It's been on my roof for 10 years feeding a 135-ft dipole antenna, run 100 watts. I've talked around the world. Only negative, obviously if it gets wet you can forget about a usable SWR. I actually have some ladderline I can replace it with, but why bother? Seldom rains in NM.

Comments about RadioShack 100-Ft. 300-Ohm Flat Twin-Lead Cable:

Would have no issues using this for HAM radio applications. I prefer using 300 ohm wire for amatuer, FM and TV applications. Everyone uses coax and they are missing the boat. Balance line, properly installed, is the best way to go for antennas. If you are installing a HDTV antenna, go with 300 ohm and use a balun at the set. Good price. Wish Radio Shack sold 18 ga. too.

Comments about RadioShack 100-Ft. 300-Ohm Flat Twin-Lead Cable:

As a Ham Radio operator I found this was ideal for connecting my BIG dipoles to the ASTU. I operate almost exclusively at QRP power levels but have run it 100 watts with no observable problems. Useful to "prove" an antenna design before I invest in the more costly 450R ladder line.

Comments about RadioShack 100-Ft. 300-Ohm Flat Twin-Lead Cable:

Not for ham radio? Boy am I in trouble. I do not use coax or 450 ohm line to feed my dipoles. I use this. I run it from the balun on my tuner to the center insulator at the dipole. The dipole than tunes everywhere from its 1/2 wave resonant freq. and up. Did I mention that I run QRP? Maybe a stretch on QRO - but I would try it with 100 watts.
