Gene Let us know how it all turns out. I have been stumbling along with an 160m inverted L and having mixed results. The first one (with linear loaded horizontal section) seemed to work o.k. but the
Hello I do not want to flog the proverbial dead horse but I am trying to understand something here. My inverted L for 160m seems to work fairly well but the tuning is far from o.k. Right now I have 5
Hello Thanks everyone for helping this new guy out. As I said before, this is my first hf vertical project and I have a big learning curve ahead. The main things I've learned so far: 1) You can't hav
Hello all After the swr fluctuations due to wet weather and ground radials, I made a few changes and made some headway. I had a temporary feedline section about 10' long from my remote switch to the
Tom I haven't tried any high power yet. Actually I am still getting over the flu and untill my voice comes, back I am mostly monitoring. The UNUN I picked up is rated at 2kw pep and 1kw continuous. I
Ragnar Sounds good to me. I haven't kept in practice so I am slow. Maby someone out there will suffer through a slow contact or two with me. JerryC KC8TES -- Original Message -- From: "ragnar otterst
Hello all The Ryerson Tull steel stock list gives 2" od.x 1/4" wall tube a weight per foot of 4.673. At 20' long, that is 93.46 pounds. Some alloys do vary and I don't have the chromolly listing but

Bill If the swr meter is between the antenna and the tuner then you are not reading the swr the radio or amplifier sees. The proper place for the swr meter is after the amplifier and before the tuner
When I built my house some years back I found that my local government office that issues building permits had a copy on display for anyone to look things up. They also had the books for sale. Anyone
Tom I may be wrong but my take on this is that many of us were told that structures not properly grounded would build up static and be more likely to attract a strike. I have also wondered about the
Tim Loop perimiter length and corner positions determines the lobe pattern. You don't necessarily have to worry about the corner angles. EZNEC will give you plot patterns and all you would need to do
Tom My loop testing has shown problems using an odd multiple of a quarter wave feed line. I ended up using just over a 1/2 wave on 80m to a remote balun with about 20 ft of coax into the shack. I tun
Maby I am just trying to over-simplify this but what would be wrong with connecting a 50 ohm. load to the far end of your 75 ohm hard line, putting a section of rg213 (or your favorite 50 ohm coax) o
Rob Seems most people using a UNUN (myself included) are using it to transform the 50 ohm feedline to match a low or high Z (but resonant) antenna such as a ground mounted vertical or inverted L. I u
Joe Better check with another supplier. We regularly use galvanized bolts and we never use anything less than grade 5. Grade 2 is just too soft and results in too many broken bolts just tightening th
Hello all I am one of those unable to afford the 20k ground system. That said I am unwilling to settle for just a couple of ground rods either. I want to keep lightning out of the house not to just p
