Wow, great site.  Thanks Corey.  They have a lot of classic radios.

Hello, I am not a ham radio operator but my father was at one time. He is in his late 90s now and my brother has been going thru our dad's basement here in Columbia . He found what looks like 2 old ham radios and a couple boxes of vacuum tubes etc. My guess is the radio is from the 50s/60s. 

What are my options with this equipment?  Is it worth trying to sell, (have no idea if it works) or just junk it? Would there be anybody in your org interested in looking at this radio? I have attached a pic of the radio to give you an idea what I got here. Can get better pics if needed.

Thanks for your time! -TJones

If one could look where the radios came from, you might have a chance of finding the power supply,  after all it does not look like a radio. Just a green box with wires.

I would recommend that you get with Fred and make up the 450 ohm one as a good start.  You are welcome to my stash.

As an admitted noobie, you are in for "the ride" into the black art (almost) of antenna design.  Mostly we all start with cheap and simple and evolve into personal circumstances and needs.  You will find an abundance of expertise and help from the CMRA / BCARES group.  Online sources are also great.  Allow me to encourage you on.

How much do you need.? I got quite a bit left over.  Don't know exactly how much but I just looked at it and it's a sizeable roll.  I have a j-pole made of this (made by Fred, in fact) and it's only a yard or so in length.  I think I have enough for dozens, at that size.

Free for the taking, but I don' t get out much (health problems) so you might have to come out and get it.

Fred's note refers to a j-pole.  J-poles are a good way to go for 2-meter for 3 reasons (at least) - cheap, effective, and scaleable.  Fred's design using 450 ohm ladder line is the smallest and most portable I have ever seen .  Larger ones made of copper tubing are also cheap and less tricky to tune, but still sort of portable.

I would recommend that you get with Fred and make up the 450 ohm one as a good start.  You are welcome to my stash.

As an admitted noobie, you are in for "the ride" into the black art (almost) of antenna design.  Mostly we all start with cheap and simple and evolve into personal circumstances and needs.  You will find an abundance of expertise and help from the CMRA / BCARES group.  Online sources are also great.  Allow me to encourage you on.

How much do you need.? I got quite a bit left over.  Don't know exactly how much but I just looked at it and it's a sizeable roll.  I have a j-pole made of this (made by Fred, in fact) and it's only a yard or so in length.  I think I have enough for dozens, at that size.

Free for the taking, but I don' t get out much (health problems) so you might have to come out and get it.

Re: J-pole dimensions using 450-ohm window line resenting reply

Hello, Henry

My name is William KE0PKO, I am a new Ham and was talking with Fred at lunch about making my own antenna's and teaching my kids in the process.  I myself have been dealing with a lot of medical problems this year and can't afford to just go buy a starter antenna.  I live in the country and have the freedom of being able to build and toss up different type's of antenna's in the tree's or in the open from poles.  I would like to build a few different types of antenna and learn as we go.  I was wondering if I could get some of that 450-ohm line from you.  I would gladly come and meet you.

Short the "bottom" of the j-pole, and measure up from there:
30 mm from bottom - this is the 50 ohm coax attachment point
453 mm from bottom - this is where you remove one of the conductors all the way to to the top
1402 mm from the bottom - this is the top of the j-pole
