This was the easiest to follow instruction video I have found for this antenna yet. Was able to build it with extra stuff laying around on a lazy Sunday. Lost nothing, gained a well working antenna and some knowledge. Thank you sir

What are your thoughts on sliding a couple foam pucks with center hole down the pipe to keep the coax and wire centered inside the pipe?

After placing the foil tape, you can press against it with the sharpie to smooth it out.

I am pushing 25 watts thru mine (mount on the roof ... but the SWR moves about if the wind flex’s the pipe.

I made one of these a few years ago It tunes well and works well mounted above the roof line on my house. The only downside is that the pipe wall is thin and it does flex in the wind. This causes the SWR to move during operation.

Maybe it would be an idea to put a cane or dowel rod in the centre to give the pipe a bit more rigidity? I don't think it would alter the operation of the antenna.

There is no way that it 1" pipe. It looks like 2". The paper you got the plans from says 1" (25mm) but 1" is about the length of the end of your pointer finger and that pipe looks to be double that. I really hope you did use 2" and got those results because I just happen to have a 4' long 2" pvc pipe I want to use to make this since I just got an old Kenwood TR-7800 in mint condition I want to use it on. Plus I could use it on my dual band HT as well.

It turns out a vertical dipole for 144 MHz and a dipole for 433 MHz. However, there are doubts that the aluminum foil should be closed around the circumference?! If it is not closed, then it will not have a shielding property.

Mine worked well closed, I am not sure about being open but it would be worth a try.

Why is the lower part shorter than the upper part and how did you know how much shorter? How did you determine 9 turns in the coil?
@buddhistsympathizer1136
6 ай бұрын
I believe the lower section is shorter to take into account the velocity factor of the radiowave in the coax. 9 turns in the resonant choke is chosen for a frequency of about 135Mhz - just below the band of use (it is an inductor).

Very nicely done! I am confused at how the fold does anything without being connected to the coax?

From what I understand it acts like a choke.

Why wouldn't you just use the center conductor of the RG58 antenna cable measured out o the proper length instead of soldering a piece of 14 ga wire in? it would seem to me one less joint to possibly fail. Just curious.
