Hey, John! Nice article on the UL external antenna mods -- thank you.

Have you checked to see whether the turns wrapped around the ferrite
bar for the jack effects the alignment tuning of the bar? I am
particularly interested in the SRF UL, since I have a '49. (Does that
make me a "49er"?)

Seems like it would be best checked with the external antenna connected.

If this effects only the overall sensitivity it may be a moot point
with "big sigs" coming into the set from outdoor antennas.

What do you think?
