Post by Gunner357 »

Finally After 40 years of not having a base station( I had one as 18 y/o...) Im gonna have one,Yes I have my Mobile for years But its not the same as a Base..... V58 Maco finally tuned 1:1 just got to find some help to get up to the roof and figure out how I'm going to mount it to the roof (No tripods) the house is a little different than a std cable house.....btw How high before I should think about GUY Lines..... Ill have 20ft of mast and the rest will be the house totally about 45 at the radials of antenna......

I like to run a mast from the ground up using 4" or 6" standoff's to the house. Several around me are using those push up masts. I think 20ft above the last mounting point is too high not to be guyed, I would think 10ft is max and 5ft would withstand high winds. I use rigid aluminum (sch40) 1 1/2" id for my mast. JMO.

My piece from the antenna ATM is fence pipe 1 1/4 OD Its thicker than regular mast pole...and the only size that will fit the base of antenna I dont have any place around the house to run it from the ground do to house configuration and a Big tree thats why I was going to use the house as part of getting this thing in the air so 20ft of poles would be my max off the roof of the house even 10 would get it to about 35.....

I ended up using the 1 1/4 x10 fence bar from antenna down to 15 ft of 1/3/4 steel structure pipe I bolted all the sections together I'm aprox 3 ft above peak of house good enough for me at least for now I used EMT straps at the cable eve and will make some mid brackets up... the base I left in the cast iron deck umbrella base I still need a ground rod Im on cement so I need to figure which direction to run the ground cable Other than the SWR not being where i like them it works great TX locals at a range of 25 miles To the west of me nothing yet in the other directions I did contact one of the locals On US23 25 miles he said I was coming in very strong but I could hardly pull him outa the white noise....

congrats on getting the base going. theoretically you would like to have your ant. a wavelength above ground.
I have my old 5/8 hy-gain mounted to the top of 10' of 1.5" steel tube sticking out the top of a 2" steel pipe 18' long sticking out the top of a 20' tower.
fully cranked up, putting the radials at ~46' it withstands 35 mph winds easily, lowered to 29' it took 70-80 mph wind.
its engineered it to withstand 125, which will never happen here.
no guy wires.
my ground rod is 8' long directly below, thru the concrete.
my next tower is going to be bigger, 65' , unless i go with a beam.
your setup will work and you can run the ground anyway you want. thats similar to my first pole tower,
from there i just had the "skip" bug and had to have a bigger setup.
and i still want more,,,,, is this addicting?, naaa, ;)
