Long wire antenna question

[funken]

Hi folks!
I'm not sure if this is the place to ask tis question but you all have been very helpful with my other questions.

I have a kit for a long wire antenna. I have limited space where I can string the wire. I would say a about 50 yards max.

I read somewhere if you don't have a lot of space for this type of antenna it wont be that effective.

Please advise.

This antenna will be used for my Telefunken.

Thanks in advance!!
