I often was successful by using Coke. Let it soak for a night, either in a tub or with the tubing filled with it. 73 Peter Guys with ideas... I am trying to remove a 3/4" aluminum element end from a
Hi Phil, Olflex cable by Lapp is numbered that way http://www.lappusa.com/searchstart.asp I use that on all my wiring and some km have been installed at www.DF0CG.de 73 Peter, DF3KV --Original Messag
I would not do that unguyed at 80km/h, the Pro57 is quite a large antenna. The problem is mainly to retract it on higher wind speeds, you will need an additional winch for pulling it down http://www.
My 100 foot mobile Versatower crankup MUST be guyed. I guess the additional downward force has been calculated for the size of wires and pulleys 73 Peter Maybe I'm mistaken, but I thought guying a cr
That is how the large towers of the russian contest stations are guyed 73 Peter Depending on the loads, one could use cleverly designed winches to both store the guys (in the retracted position) and
I never need an antenna tuner and have none in use, except for using a fieldday dipole as allband antenna which a built in tuner would not handle anyway 73 Peter Without antenna tuners? Nearly all mo
Hi Scott, Your problem is quite common with small diameter element tips. Insert some rope into them and the vibration and element failure will stop. I did that with my HyGain beams and have no proble
Hi Dave, To me that sounds more like a T-match 73 Peter Hi folks, Just received a new TA-33M with TAC-33K feed. I've never seen a driven element feed like this one. Its a clever implementation. Where
I coiled up about 3m of the feedline on a 4" diameter PVC-pipe, works very well on my 3 105CAs 73 Peter Any proven baluns that will work well for the Hy Gain 105CA. Tnx, Michael Mark, P.Eng. VE4MM __
Hi all, I am going to bring up my 3 element fullsize 40m yagi in a month. Now my idea is to force it into a rotatable dipole on 80m by using an omega match. I could probably run the omega tube undern
I fully agree, he will not improve above his stack of 2x3 elements with the upper at 150 feet+: http://us.f13.yahoofs.com/bc/43de01f4ma0718d53/bc/3+over+3+on+40+mtrs+at+K5G O.jpg?BCk.cEFBL.J7d8wc If
While doing the previous simulation already with HFTA, I did another one for my own location on a small hilltop, which benefits from slooping foreground, with the same antennas. Here the situation is
Yes, I think that is a better idea then cutting the jacket of braided cable for the ground strap. As well I have no problem doing that with my Heliax/Cellflex cables I also prefer there the grounding
Hi Roger, I use 3 short beverages as well, length are two with 45m, the other 60m. I found them always very useful on 160m and 80m as well during the contests. Either I hear two different stations Q5
The bobtail will beam to the wrong direction, 90 degrees off Europe. Inverted vee elements will do and have a lower elevation angle then a single dipole. Two or three wire verticals fed as an in line
I wonder whether you like to give helpful advise or make profit... 73 Peter multiband vertical. I would like to have something that would be for 40 - 15 meters. I know there are lots of options out t
And another advantage is its 5-7db groundgain. With my dipol at 100´and sloping ground I always outperform on transmit a guy with a 2L-quad@20m 150km away, of course he is listening better. 73
In Germany our rules they it has to be calculated by its weight on top of the ground. The foundation size of my free standing tower is 4,1x4,1x1,8m. 73 Peter I've been wondering this one for a while,
Why should it? What do think will improve? 73 Peter Now, if you did away with the dual driven element and make it into a 4 director antenna it would really play. _____________________________________
It must be confortable to climb with a 40m yagi 13 feet above tower, but... My rotating mast collapsed 15 feet above tower at a recent storm with 170mph gusts. It was 4,5" with 1/5" wall at that posi
