There have been reports of verticals and salt water almost as long as there has been radio. It helps horizontal antennas also. Ive operated for enough years aboard USN ships to know it is often a ban
There is a lot more to winning an all band DX contest besides a great 160M location. Tim and Frank picked locations carefully for low noise, used the various tools to understand propagation and the a
It all depends upon the propagation and the TX and RX stations. A full size vertical in salt water will have a much lower angle at or near peak power than one miles back in the woods with typical gro
A 3CX15000B7 or similar makes up for a lot of things and especially to those who always want to be on top in a pileup or contest. Carl KM1H For receiving, an absence of noise sources in the path is a
Nope but the RX antennas usually allow you dig a long way below the TX antenna noise. Most of the world isnt so lucky to have a selection of RX antennas or if they do the local QRN is too loud; anoth
That was a very interesting post Mark and thanks for taking the time. In the mid 60's to 80's I was very interested in LF and MF BCB DXing and at first I had a loaner HRO-500 (I worked at National 19
Do we really care that skimmers aren't hooked up to antennas with pattern and gain? One of the things in using VOACAP is knowing the pattern of the RX antenna as well as TX. Omni pattern at RX remove
BC antennas have the elaborate radial system in order to get that groundwave while the typical on ground ham vertical loses a lot of the 0-10 degree (or more) radiation. Go to the beach to get it bac
That just isn't factual at all. Radials under the vertical antenna have virtually no effect on wave angle unless they are sparse and grossly unbalanced, allowing them to radiate like a low horizontal
Radials change the efficiency, not the pattern, unless the radials radiate like a dipole. I agree completely with both of Tom's posts. 73, Jim K9YC You should, he didnt say anything wrong. __________
Anyone know if the ferrite beads that are encased on the cables of older CRT monitors are any good for use in the shack. This has probably been asked before but I can not find any info. Thanks , Joe
The first info needed is are the guy wires insulated from the tower and what is on top including mast? Carl KM1H I would like to get on 160 this question most likely has been asked a 1000 time but I
Which is the same height as the one I had in the 80's at another home. With stacked 10-15-20 W2PV-4's it resonated somewhere around 1530 KHz if I remember and an Omega was the only thing that worked
All I had on my tower were the 3 coax cables and rotator wire which were all taped to the tower about every 5' which apparently decoupled them. The coax also had about 15" of large 43 mix ferrite bea
Im going to be needing 500-1000' spools of polyester double braid rope for supporting some more wire antennas in the harsh enviroment up here. The 5/16" is rated at 3400 tensile and the wire will be
Thanks to all for the suggestions. Ive been using the Synthetic Textiles since the 80's when it first came to my attention in a YCCC newsletter and have been very pleased with it. Price from DXE is $
Ive been spending a lot of time trimming and removing trees around my shorty 60' tower which was the first one up when I moved here in 89. It is amazing how fast they seemed to overtake "my space" in
Ive been stretching copper since 1967 with lawn tractors since buying my first home; 8 acres and about 3 had to be mowed. I suspect well pump wire may hard drawn but I'll give a small piece a test fi
Not according to the folks that invented them Frank. The Big Grip is a Guy Grip for serious towers. http://www.preformed.com/index.php%3Foption%3Dcom_phocadownload%26view%3Dcategory%26download%3D44:p
Sounds like a lot of Nervous Nellie knee knocking to me Tim. Caution within reason is a good thing, understanding that all Rohn tower specs plus PLP and other hardware providers are extremely conserv
