K9AY works well (with 3 grounding rods but not one). Much better than vertical or dipole to EU but noisier than an inv L to VK. I am thinking about receive 4 square. Will it work within elevated radi
I was planning to buy a 4 sq receive system for the upcoming CQ160 contest. One question is about handling of high power when the 4sq cannot be put far away from the tx antenna. HI-Z claims that thei
HI-Z is not selling so I am asking whether anybody has used Hi-Z for sale? All except HI-Z 8, for which I have no space. Ignacy, NO9E _______________________________________________ UR RST IS ... ...
I listened to the ARRL 160m contest in VK2 in 2006 and in 2011. In 2005 I heard many NA stations clearly. In 2011 I could hear many NA stations but strong static prevented copying complete callsigns
I have received a used 3-el HI-Z but without the phasing line. What is its electrical length? I saw some notes that it should be 27 degrees long. But this is frequency dependent. Urgent question as i
Thanks a lot. I worked 470 QSO in CQ160 so far using K9AY but I missed a few ones possibly multipliers. Hopefully 3-el HI-Z it will help tonight. Ignacy ______________________________________________
I homebrewed a magnetic loop for diversity reception with Hi-Z 3 el. in K3. For perhaps up to 1000 miles the loop provides excellent separation between signals from Hi-Z. But it hears distant station
I have an 80m full-size wire vertical and 160m inv L using the same 8 long elevated (and tuned) radials, each 20m long and 2m high. The RCS-4 switch picks up either antenna. Having separate feeds mak
A number of articles analyzed 160m verticals by simulation. Once the height was lambda/8 and the number of radials >= 16 (buried) or >=4 (elevated), the difference in gain was at most a few db. I ope
I would like to share my experiences with 160m operations during the SP contest last December. My rental house in St George Isl FL had a 140 ft pier over the bay. Also a power line to the end of the
There was a report from an expedition where the radials in water did not work well but over water did. Over salt water, one radial (counterpoise) is enough and more do not add performance. I used Exp
I operated on a pier over salt water on 160m in 3 locations. Once with baloon for an inv L. KW with short antenna creates special problems. See my message yesterday. Short radials will have extremely
Lately when I worked a VK on 160m, the transmit antenna antenna heard better than beverages. In other cases with the VKs, the beverages were better but not by much. I am wondering why this is the cas
Interesting observations with dipoles and high angle of arrival at sunrise/sunset. But from graphs, the beverage also has a fairly high radiation angle. I am wondering whether anybody has compared be
Now for 2 weeks my QTH hears a static-like S9+ noise on 160m, 80, and to a less extent, 40m. No static heard on 30-10m. Makes 160/80m bands useless. Beverages and 4 sq point to the East. Seems the st
My shunt fed tower has 36 radials 70 to 100 ft long. Would adding a few longer radials towards EU help to EU? Eznec says no. Ignacy NO9E _________________ Searchable Archives: http://www.contesting.c
Did anybody try SO2R or SO2V contesting on 160 with Flex 6600? Normally I use diversity of the main TX antenna and beverages. With the TX antenna most of the signals are readable but weaker ones are
Do more radials on a 160m vertical bring more improvements than shown by simulation? Most simulations, e.g. by EZNEC, show that going above 32 radials on 160m brings minimal improvement, say 1 db to
I have a 100 ft tower with jk mid tri 40 on top. When shunt fed, it was pretty competitive on 160. Recently the antenna seems to be a few db weaker. The only change was adding another beam at 60ft. C
In a number of QSOs recently, other stations made easy contact and my station struggled. I make sure to exclude stations on the east coast and those with 4sq. Ignacy NO9E _________________ Searchable
