Hi guys These are interesting question about ground or should I say "ground" . The answer for both question is the same. First we need to clearly understand what ground means, here some basic stuff.
<<There is no need for the antenna to be over water for that benefit. >> Hi Grant I don't know how many antennas do you install, I mean yourself. We all respect this concept is just wrong. 73's JC __
There is a fine line between "know" and "believe". Like detuning your tower, directivity increase signal to noise ratio. You need RX antenna on 160m in a quiet place. Antenna over salt water is one o
Guys Some concepts really belong to the last century, a beverage antenna is very inefficient for moderns days. Ground wave noise is very high everywhere and it is vertical polarized, any vertical pol
It needs a long, very long answer. Please feel free to edit, correct this text, share with you club and publish it here again Let's start with some basic definitions and assumptions. 1- Receiving sy
Here in Florida the KH1 signal on 160m was much better than 80m. Almost everyday it started s3 after an hour it was s6 to s7 and some days peaking s9 near sunrise. At the same time on 80m, the signal

Hi Bill I noticed that too, long path was very different past solar cycles. I am not sure if long path happened the same way before 2010. During 2010 to 2011, I heard and worked XU7ACY 50% of the day
Hi topband lovers The internet has become an example of bad practices resulting on wrong conclusions. Opinion are drawing based on anecdotes results where the antenna is the problem, not the lack of
A BOG is an excellent choice when stealth is the driving requirement, otherwise arrays of short verticals provide significantly superior performance compared to BOG or short Beverage occupying the s
<< Sometimes the YCCC is better and sometimes the BOGs are better for 80m or 160m. That's for me is a very low performance. The good Horizontal Flag can dig signals 22 db below the vertical TX array.
Hi Jerry If you want to play with a very high performance EWE array, you can try this one. 5m high , 7 m wide, 7m spaced, 4 EWE's in line. 49m total. 1st EWE 10 degree 510 ohms 2nd EWE 190 degree 540
Hi Guys Stay away from aluminum, the aluminum oxide dielectric is a terrible complication around 2 MHz, it become a capacitor and a diode and will generate a lot of noise in presence RF currents. The
Hi Guys, here my two cents. Radials are important to increase the power gain. The directivity gain is the same. More efficiency means more irradiated power, just it. Steve TX antenna may have 50 % ef
Hi Ed One of most impressive study about Tree and antenna performance was presented few month ago by Dr. Kay Siwiak, KE4PT during the South Florida DX association. The study was based on years or res
Hi topband lovers The good days of 160m propagation is back! T88UW signal was real 569 10 minutes after my SR. Ichiro is running 100W and a sloper antenna not so high. Robert DU7ET also with good sig
Just a remind that any tower few miles!! away needs to be detuned to avoid pattern distortion. Like cellphone towers. It is the same for 160m TX tower or arrays, every tower is an antenna on low band
Hi Pete I don't understand why Beverage at first place, A rotatable Vertical WF can perform 11.5 db RDF on 160-80-60 and 40m rotatable on any direction and it take only 50ft maximum. If you want high
Hi Roger I used a dipole for several years too. Actually took me 20 years to work my first DXCC on 160m from SPaulo Brazil using them.. Here is the thing, your horizontal dipole is not 100% horizonta
Hi Dave We just can wait for it. Patience., good conditions is coming to stay for several years. 73's JC N4IS --Original Message-- From: Topband <topband-bounces@contesting.com> On Behalf Of daraymon
