After reading several articles both on and off the WEB regarding a
center fed antenna, only one article mentioned a recommended length for
the feed line.
My shack is located on the second floor of a new home, (24') #8 ground
wire to 8' ground stake with a further connection to the common
100 feet of ladder line is sort of a magic number for being
easily tunable on all the bands. One of my friends bought
a ready-made 80M dipole with 100 feet of ladder line and a
tuner; and the instructions were not to cut much if any off
the ladder line. I learned the reason for that later when I
This is quite off topic, but hopefully the moderators will cut some
slack since even digital ops want a good antenna like anyone else:)
I do have some experience with using a modified form of W6JJZ's, The
Suburban Multibander. This antenna is described in the ARRL Antenna
Compendium, Volume
I have used that multiband antenna configuration both at my home station
(140' doublet, 450 ohm ladder line, 1500 watts) and when travelling (70'
doublet, 300 ohm TV twinlead, 100 watts). My experience:
1. Balanced tuners (e.g. the Johnson Matchbox) work better than an
unbalanced tuner and a
Where practical and available, instead of using a split-core ferrites, use a
ferrite toroid. The split core will never achieve the level of magnetic
coupling between the two halves that the toroid will, with its continuous
magnetic structure, and all else being equal, that makes the toroid a
If most PSK operators are interested in rag chewing -they need to move
on to a better digital mode. PSK and RTTY are the two worst modes
available. And that's the problem. Too many people, groups, and
leaders in the Ham Community promoting OLD and less than effective
modes of communication.

The subject came up about RTTY of who was using what program.
I was listening to all when I was ask what I use. My answer opened

On what basis do you claim that Olivia, DominoEX, and MFSK are better than
PSK for ragchewing? Olivia is slow, and MFSK is difficult to tune. By
design, DominoEX addresses both of these issues, but at the expense of
increased bandwidth -- which makes panoramic reception less attractive. You
Its difficult to make a QSO in the newer modes because they aren't better
enough than PSK or RTTY to motivate a broad-scale transition, so their use
remains limited to a small number of afficianados.
When someone develops and deploys a mode with significant improvements over
PSK and no
