The beginning of the new Topband season looks very promising.

I have two bidirectional 720 ft beverages that use 450 ohm ladder line,
oriented NE-SW and NW-SE. The ladder line is supported by 4x4 wood posts,
about 7 ft above ground, spaced every 60 ft. The antenna works well, but has
turned out to be a maintenance nightmare. My first mistake was to anchor
Agelos, conditions appear to be very spotty. I was QRV at that time and
the stations in the midwest (W8s and W9s) were working MD0CCE with ease
while I was strucggling to hear him. He finally did come up out of the
noise long enough to work him. There were also several other spots that

ok. RG6 would be stronger, but might have a bit more loss with the
copperweld center conductor, but that usually isn't a concern.

Hi Jim,
One other effect that fools sensitive DMM's on their resistance scale,
is the electrochemical voltage that gets developed between the ground
rods used for Beverage antennas. I also experienced gross
inconsistencies when trying to check for breaks using DC resistance checks.

Hi Topbanders,
Tomas, VK2CCC, wrote a great report VK9LL story 2013 with a lot of
comments, technical info, links and nice pictures downloadable as a PDF file
from this page of my website: http://www.iv3prk.it/vk9ll---2013.htm (Sorry,
he said his server is down).
Apart from having worked
Similarly, you can parallel a lower capacitance air- or vacuum-variable with
the fixed micas. The ~100pf HV variables are much less dear. Same end result.

Hi,
is there a rule of thumb on spacing and dimension (in terms of diameter)
of a Gamma match to match a tower for 160m?
The tower we want to try to use for 160m is about 196ft high, basewidth
is 18.5ft, at 196ft the width is around 5ft.
Thanks,

Many of us have had similar experiences with ladder line, even copperweld.
For more longevity, consider using MilSurplus field phone wire WD1-A. With
a mix of steel and copper strands, the wire has good strength - and seems to
hang in under ultraviolet condx. I've used it on my
I was doing some e-mail follow up on 160m QSL's sent and not received.
One of them was for YE1C. I assume others might be needing this QSL, so here
is some information.
The new manager is YE1NZ.
This is his response:
Hi Niko,
First of all, please accept my apology for never getting the YE1C
Whatever you use for wire, it needs to float at the supports. Anchor it at
only one end and tension it tightly at the other end.
I use my own ladder line, made from .061 diameter plated steel electric
fence wire and spacers made from 1/4 dia. plastic coat hangers. Supports
are 10' high and 100'
