Yes, and you can see this difference in mfr data sheets that are
sufficiently detailed (Belden, for example). The differences are
greatest at the lowest frequencies.
Note
Ken, Some DSL service use frequencies in a higher passband then the
standard DSL modem uses. See W8JI's site for a detailed explanation on
this. My Westek TC-Z100B1 did virtual miracles for me after trying many
other solutions. My system is not a bundled ADSL-2 so the passband and

Hi everyone,
I would think that there's a high correlation between the polarity of the IMF
and the K/A indices, so this polarity may not tell us any more than the K/A
indices. There is a topbander on the other side of the Atlantic (darned if I
can remember who it is at the moment - as soon as

Obviously I had computers on my mind...
Yes, of course I meant to say quad-shield RG-6 CATV cable. I'll provide the
manufacturers and part numbers in a subsequent e-mail, but its just typical

I had seen when those factors a long with a full moon or new moon that

All the other factors have to aline and if the sun just does not cooperate
we are just SOL.

Hi Topbanders,
I have it behind me the same troubles with mute my ADSL.

Thanks Boyle OZ7C for your help.

Absolutely there is a very strong correlation. I suppose it comes
down to what
Steel, being magnetic, is quite lossy at RF.
OTOH, aluminum at RF is only 28% lossier than copper.
However, no RG-6 (AFAIK) has a copper clad aluminum conductor.

I successfully use 100s and 100s of feet of copper clad steel RG-6 in my
160m 4-square receive setup with a pre-amp at the station. Copper clad
steel works for me.

Think of all the ways you can hurt yourself laughing.

Today I measured the difference in loss
I posted earlier on the list (31 January 2011 ) problems we had with some
cheap ebay satellite cable CCS RG6 that I was using on a long run to 160m
Beverages. The 250m reels came from different suppliers, though both of Chinese
origin.
The measured loss in the first 250m segment was ~ 6dB
Hi Doug,
Quad shielded RG-6 with a copper clad steel center conductor is an excellent
choice on 160 and 80 meters as long as the cable lengths aren't very long.
Outdoor rated quad shielded CCS RG-6 is more readily available at low prices
(typically less than 10 cents per foot) than solid
My DSL is from U-verse 3K. I'm near the end of the line, it comes in fiber to
about 1/2-mile of the house then thru 45 yo phone wires. With the filter in,
160 RFI is cured but there is considerable loss and S/N reduction.

One of the reasons I have mot gone to high power on 160 is the cost of
capacitors for my omega match - at least $300. Anyone know of any
workable alternative? I remember someone writing about using coiled-up
RG-8, RG-213 or maybe Teflon coax. Where can I find more information?

As you guessed - VO1 should send NF and VO2 should send LB.
We should make that more clear in the rules perhaps.

At KC1XX we also have a 1500-foot feedline run to one of our lowband
receiving antennas. We use RG-6 with copper clad steel center conductor, but
we install a preamp right at the antenna to compensate for feedline loss and
some passive splitting losses at the station. A potential downside of a

Several topbanders asked if I would measure the DC resistance of the solid
copper and copper clad steel center conductors of the RG-6 coax for which I
published the RF loss measurements. I also measured the quad-shield DC

I used a big 300pf breadslicer with somewhere in the 7.5 to 9KV range ( I

Smaller spacing and lighter duty fixed caps didnt survive the 1200W of my
own amp but the rebuild
