Newbie question regarding wire antenna

[VK5SWL7]

Hi everyone,

I have a question regarding whether or not it would work if i ran 1 leg of a wire dipole alongside an existing wire antenna.
I have an existing wire antenna run from my house to a pole mounted on my garage. I can install a 40m wire dipole using the pole as the centre point. This would mean that 1 leg of the dipole would be run close to the existing antenna.

My question is, would they interfere/interact with each other causing problems or would it be ok? I am currently listening only, so at this point, transmission problems do not apply.

I apologize if this topic has been done to death, but i would prefer not to make a newbie mistake if someone is kind enough to help me out. Any assistance would be greatly appreciated. I built a 9:1 unun for the wire antenna and would need to build another balun for the dipole. (i think?)

Cheers, Steve

Hi Steve

Welcome to the Forum.

If I've interpreted things right, you won't have a problem.
See figure 5 in this extract from the ARRL Antenna Book.

Same principle also gets a mention here: http://www.hamuniverse.com/shortwaveantenna.html

If you can obtain copies of recent editions of both the ARRL Handbook, and the ARRL Antenna Book, then that's all the reference material you really need.

Hi Adam, thank you for responding. I will indeed check out those references. The wire antenna is connected to a receiver in the house and the dipole will be connected to a receiver in the garage. I will only be using one of them at a time. This means that from the pole on the garage to the house will have a wire from the dipole and the wire antenna. I hope that makes sense. Thanks again for your help, cheers, Steve
