Hi, ThomasThanks for bringing N9NB's antenna to my attention. It looks like it might do a fairly good job for hams with limited antenna space, especially height. It may be worth your time to at least

I like the delta loop a lot better than the dipole- but why not select the feed point for vertical polarization? You should get better results if your intention is to DX with it. W8JI has a dipole at

I had a similar experience with a "U"-type antenna on 160m, one big difference being that the horizontal length of mine was 140ft instead of 100ft. At one time, I had an 80m half square up- about 68-
Hello, TopbandersJust a quick note to mention that my Flag and Pennant resource is back up and running. I think it is great that the guys at contesting.com allowed Major Domo to retire with full pens

The other day I saw something quite ironic at our local post office. There on the door, a bright red sign with white lettering was posted. It stated that cell phones are banned inside the post office
and then there's Litz wire ... http://www.dartmouth.edu/~sullivan/litzwire.html The referenced web page says Litz wire is used to good advantage from about 5KHz to 1MHZ, and that is just about how I
About, "I like top feeding because the current is higher above ground. This gives a better shot over high, thick trees...etc." The current distribution in a given antenna element is independent upon
After buying my FT-1000 I became interested in doing some polarization diversity receiving with two antennas. As a quick check, I tried the Yaesu with my Kenwood TS-930 on 30 meters, using a high hor
There is a simple mod applicable to the FT-1000 equipped with the BPF-1 option, or to any FT-1000D, which allows the main tuning knob to control both main and sub receiver frequencies simultaneously.
I just got an FT-1000 recently, a late 1991 build, and have added a BPF-1 band pass filter because I want to do some polarity diversity work on the low bands with separate antennas. I'm quite familia
These lowband transmitting antenna discussions sometimes give me a headache. Is it possible that two different (but related) subjects are being intermixed here? One seems to be antenna efficiency in

Hi, DaveI hope you take the time to research it all, and get the benefit of all the collective wisdom on this reflector. Sounds to me like an inverted L would be your best bet. I am guessing that you
I recently had to fix a number of broken links on my web page connecting to various posts to the Top Band Reflector. Today I was trying to access the master list of Top Band Archives, and I found tha
Hi, Jason and Topband reflector readers I'm not totally clear on how you mean this: "(the article writer) panned the blame on ham radio operators" If you mean that hams are portrayed as the bad guys
But Current Technologies LLC, which offers BPL service in the Cincinnati and Rockville, Md., areas, can't find interference caused by its system, said Jay Birnbaum, the company's vice president and g
I remember hearing locals on 160m AM on my old Clarion AM radio sometime around 1960. This was a great old tabletop radio probably built in the 1940s or 50s which had a wood veneer case and actually
I may have an easier time working KL7 from MD than you guys in the midwest. Still, KL7 is pretty thin in my logs on top band. Digging through my DXCC deck, I turned up AL7MX, Kevin, in Wasilla. The Q
Oh, my- that is probably begging for trouble. Not only does that technically constitute trespassing, but it would indeed look very suspicious. A good, clever technique, however. I distinctly remember
This has been my experience as well. My FT-1000D does antenna diversity with a common VFO running both receivers, and the two signals are entirely separate from antennas all the way through to the st
