I have all the space in the world and wish to errect a single random longwire to use on the 10 meter band only.
I understand that once such a wire is very long, losses associated with the wire itself (a wire of suitable gauge) mean that after a certain length, there is little more to gain.
- So at what point would it become impractical based on performance?
- Also, is there some way of calculating the optimum length where space is not a real limitation?
I used the term 'random longwire' because a longwire is defined as a length of wire at least two or more multiples of a wavelength (and I made it clear that it is for single band use), and random is in reference to the fact that it doesn't have a relationship to the wavelength within.
The height is rather varied, as it will be strung over a deep gorge. Minimum height will start at a quarter wavelength, then travel for some length averaging three quarters of a wavelength. The maximum height above ground will be between 100 and 200 metres depending on droop.
