Topband: BOG Question

The bog needs to be insulated from ground. I have a bunch of old RG6 cable that I can use. Should I tie the shield and center together or just use the sheild or just use the center or use something else? W0MU _ Topband Reflector Archives - http://www.contesting.com/_topband

Topband: BOG Question

Hi Glenn,   I got my BOG working very well in the early spring time. up to 8 S units F/B.  Through the summer it got very dry (drought) here in Belfast. The F/B went slowly down to 2 to 3 S units depending upon the direction & incoming angle.   Last night we got a huge thunder shower and the

Stew,   A BOG can do a good job untermnated.   If too long they self terminate. Depends upon the soil as to length.   Check youtube.    https://www.youtube.com/watch?v=GTXvcEwgUsU    Also check ..http://www.qsl.net/k1fz/bogantennanotes/   The biggest mistake is making the BOG antenna too

Topband: BOG Question

I'm thinking of trying a BOG as I could run it across the corner of my neighbor's field (after he's finished mowing for the season.) My questions are: Can a BOG be used un-terminated and is it then bi-directional, as is a conventional beverage? In a terminated BOG, is the maximum received signal

Re: Topband: BOG question

Frank et. al, The ground does indeed affect the Vf however different types of wires/cables are affected differently and the only way to know for sure is to measure the Vf yourself. I use old telephone cable ( None of it, including the cable type, affects the spacing of elements. That was

Re: Topband: BOG question

Exactly right, Tom. Jim, if you go back and look at all the posts in this thread from the beginning --which I should have done but didn't-- you'll see. I was surprised that Frank and Tom 'made such an incorrect statement' (so I wrongly assumed, that is) before we 'disagreed'. ;-) 73, Mike

I was thinking about phased BOGs. Would the horizontal spacing and/or stagger between them, be reduced due to the Vp change from ground proximity? Art NK8X ᐧ _ Topband Reflector Archives - http://www.contesting.com/_topband

Re: Topband: BOG question

I believe there is a large influence of height above ground on VF. From a theoretical basis, this has been "known" since Wise's classic paper "Propagation Of High Frequency Currents In Ground Return Circuits" (1934). This was experimentally verified in the Litva and Rook report from the CRC

Re: Topband: BOG question

I fully agree, Chuck. I forget the actual length, but IIRC, 200' is a commonly used length on 160. 400' or 500' of wire on the earth is much too long to work right on most types of ground. 73, Mike www.w0btu.com On Thu, Oct 1, 2015 at 4:06 PM, Chuck Hutton wrote: > Frank: >

Re: Topband: BOG question

I think this is a wording issue. We all understand the difference between VF in the transmission line and VF in free space. What caused difficulty was the term "arriving at". I took this to mean "at the antenna" not free space, as there's no need to mention the antenna if the desired meaning

Does the length of a BOG scale linearly? In other words, 100' for 80M? On 10/1/2015 5:09 PM, Mike Waters wrote: I fully agree, Chuck. I forget the actual length, but IIRC, 200' is a commonly used length on 160. 400' or 500' of wire on the earth is much too long to work right on most types of
