If you dislike this stuff on HF, you haven't got the lengths of feeder or antenna elements right. It can't possibly radiate because of the opposing signals so losses are only ohmic. If its an ohm or two, it's nothing compared to the radiating resistance. Whether its Radio Shack or any other el cheapo TV twin lead, it works fine for me. There is better but it costs more than its worth.

For The Price, You Can't Go Wrong!
|
Time owned: more than 12 months

For 5 1/2 years prior to my retirement, I lived in an antenna restricted development. I used this inexpensive 300 ohm ribbon to feed a 20 meter inverted V in my attic which I used on 20 through 10 meters. I used an inexpensive MFJ tuner to make the rig like the antenna. This combination worked great with me logging many DX contacts all with 100 watts or less....often QRP.
I wouldn't hesitate to use it again if the situation arose!

Works for me

I use it to feed a 40M Delta loop. I got 100' of it for $18 bucks. It does the job pretty well. I use a sharp razor blade to strip it.

Not uniform. Supposed to be a straight flat ribbon but the rolls I've got have sagging sections (towards the sides)
Measured Velocity Factor around 0.77 (much lower than expected for 300-ohm TV twin lead)

BAD

Not worth the powder to blow it to hell!
Fragile, cheap (like all radio shack junk), and unreliable

Agree with the "5" raters

This stuff is pretty good. I am able to tune with a 1.3 or less SWR on all bands with the exception of 15 and 17 meters. My MFJ tuner doesn't like what it's detecting on both of those bands, but likes the match it gets on the others
I run a rain gutter antenna setup at my home and was able to make one contact so far (on 40 meters) after I set it up. I would not put much thought into the reviewer's who gave it a "0". Either they weren't using it correctly, or because it has the name Radio Shack, they immediately write it off as junk. RS does do things decently from time to time and this is one of them.
I will give another review before summer is over to describe more of my experiences with it.

I have used this Radio Shack twin lead on several occasions and it works great for me. SWR was good and tuned up good. Pretty good price too.Not the best in the world but it works well 73, Jim

Great ladder line
|
Time owned: more than 12 months
|
Don't know what the last two posts were doing wrong, but I can't say the same.
I've been using Radio Shack 300 ohm Ladder Line for several years now, and have had great success.
Even built a Full Wave Loop, and installed it upstate New York on property @ 2800ft above sea level, and has endured extreme winter weather. Not cracked yet!
Used in the New York city location where it runs up aluminum sided house across tarred roof top, and up mast to wire antenna. I've run 1200 watts through it, and never a problem!
Cheap and yields good peformance like 300 ohm should.
Good enough for me and cheap. My supplier is Radio Shack for 300 ohm ladder line.
73!

Garbage

The Radio Shack 300 ohm (TV) twinlead is very lossy and breaks easily in the wind, due to the small diameter of the enclosed stranded wires and also as there are no slots cut in the insulating material. It also reacts to surface moisture and dirt, which throws off it's characteristic impedance.
If you want high quality low loss Ham Radio 300 ohm window line get it from the R.F. Connection.
