Hi topband lovers Some friends contact me with deep concerns about the next Bouvet DX expedition receiver antenna called SALAD <http://www.lz1aq.signacor.com/docs/active-wideband-directional-antenna.
Doug NX4D asked me to add his comments, Hey JC and Topbanders, This is meant as a suggestion, not a criticism. The reason I sounded an alarm to JC was the concern that the proposed SALAD/ LZ1AQ 160m
All interesting. But let me ask (and standby for flames) what is wrong with them simply listening on the TX antenna? I know, I know, conventional wisdom says that you can't possibly work 160 DX with
Wes I missed the second question. How a receiving antenna can help on your signal there. The RX antenna is good as the directivity or RDF. Based on my measurements and extensive experiments with the
I understand Wes's point quite well. I have friends who operate 6M from very remote places where there is no local noise to light up rare grids. They're rare because no one lives there to create nois
I was one of the 160m ops at "nearby" FT5XO. I can tell you that when the WX was good the TX antennas worked very well for receiving. When the WX turned bad, such as during the snow storm we worked t
This antenna will not be effective on TB regardless of the preamp used. Hopefully they won't be fighting much noise allowing the TX antenna to hear reasonably well. 73 and Christmas Blessings/Happy
Rune has kindly spoken up, making some of this discussion moot but I will continue anyway. I appreciate everyone's comments. With respect to Jim's concerns about QRM I have thought about that, but di
Thanks Charlie for the insight. I just rewatched the video of your expedition. Very cool, no pun intended. Sorry I wasn't a topband guy back then. Just worked you guys on 20 CW and SSB. I worked
Yes, the advantages of having good Beverage antennas in addition to an inverted-L are very well established indeed. I (and thousands of other Topbanders) can vouch for that from personal experience.
You need to drain off the snow static etc. with a resistor in series with a proper RF choke. The values are on this page. And buy the Ohmite resistor specified! :-) https://web.archive.org/web/201811
Oops! DON'T use an RF choke for a single-wire Beverage. Just the OY 470 ohm resistor to a good RF ground. Sorry. 73 Mike W0BTU _________________ Searchable Archives: http://www.contesting.com/_topban
All, Kindly direct questions to this group, and not to me privately. TIA. 73 Mike W0BTU _________________ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector
With all due respect there is an awful lot of presumption here. Not everyone has the space for one or more Beverage antennas. I have 1 3/4 acre but the way my vertical, HF tower, house, neighbors'
Yep. I have 8.5 acres, and it was tricky finding suitable locations for a pair of full-wave reversible 160M Beverages oriented to EU/VK and SA/JA. Feedpoints and terminations of both are at limits of
There's no need for a lot of real estate to get good RX performance. The Hi-Z three element and four element phased vertical arrays have a small footprint and yield a worthwhile and useful RDF. The
In my experience, a DXpedition does not need an RX antenna on 160 for the first two to three days. During that time they are working the big guns with strong signals. The RX antenna is needed to give
Thanks for this George. When I posted earlier I said: "Looking at my chances of working 3Y the optimum time is their sunrise (~3:30Z) when I am in complete darkness and straight across the terminator
I had an interesting experience along these lines back in 2006 for the CQ WW 160 CW contest. Following the lead of K6SE and others, I got permission from the Bureau of Land Management to operate from
