I don't think you're missing anything. It was a good question. Please also see Clay's reply.

Okay, and thanks to all for the info which I will save.

What made me curious is that twin lead is stated in steps of 150 ohms.
IE. 300, 450, 600.
I assumed it was to match the impedance of certain antennas such as a
folded dipole, etc.
Since I understand my loop to be a non-resonant antenna, and using a
manual tuner, I thought
I'd be okay to change the spacer dims, but I wondered if I was
over-looking something.

Thanks again,

Forgive me for the OT, but there are many antenna people here above my
pay-grade.

I need to replace the spacers on my ladder line.  If I deviate from the
standard spacer length for impedance
(separation between conductors), are there problems I'm not thinking
of?  I use a quality manual tuner, and
an 80 meter delta loop.

Perhaps it would be best to reply off line for this.  Thank you in advance.
