I didn't ground the mast. Or the antenna, my equipment is grounded though.kind of. Lol. I operate portable frequently and don't ground those set ups, so figure why do it at home.

Hello, Thank you for the video. I would like to build a 6, 10, 12, and 15m trapped dipole and think I have the trap part down, but I would like to know how I calculate the (electrically shorter) parts of each segment. Is there a formula I missed, or is it just trial and error. Thanks again for the video.
@kj7iaz6 ай бұрын
In the video, I mention the website I used. In the calculations there is an effective length of the trap, just subtract that from the length you would cut for a dipole. As you move out, it adds up. So you'll have to keep track. It'll be close and fine tune by slowly trimming. Hope that helps. Feel free to email me if need be, I can maybe explain better.
@ccdanieldb6 ай бұрын
Ok I got it, the webpage tool you pointed to suggests the effective length. "The Effective Length is the estimated amount that the next-lower-frequency leg of the trap antenna must be shortened to obtain resonance"
@ccdanieldb6 ай бұрын
@@kj7iaz Am I wrong? After putting this down in a spread sheet it looks like I may not be able to use the 12m and 15m bands after the 10m band. The length of wire needed gets negative when the bands are too close together.
@kj7iaz6 ай бұрын
10 and 12 are delicate. 10 and 15 should be ok. You can play around with the diameter and length of trap. Find get a combination that has less effective length. Also. This is only one way to build a trap. Could try a different version. Or experiment on your own, a trap is simply an inductor and capacitor in parallel. You could also do a fan dipole, it might work better for the bands you are trying to use, or even a hybrid version. Use traps and fans.

I used coax as per the instructions I used. A trap is a tuned circuit with inductor and capacitor. So I think with coax it's giving it more of both. Sorry I can't be more exact haha

Since this video is 6 months old you have some user data. How is it holding up in the wind? Any collapsing of the sections? What do you have on it?
@kj7iaz7 ай бұрын
I have not had any issues aside from tightening one of the lower sections a bit. I've had several wire antennas including the fan dipole and trapped from my videos. No issues with the mast, very positive towards it. Lots of wind and cold weather up here too. Nothing but good things to say.
@Hank_W6IR7 ай бұрын
Yes I have one. I had to put screw clamps on all the sections to keep it from collapsing in the wind. And even then it appears to have shrunk about a foot. I have a 2/440 antenna on top along with a small crossbar and inv vees for 80-30 hanging up there. As well as wire for an inv L for 160. If it shrinks any more between now and summer I will probably drill holes thru each section and use a bolt/cotter pin to keep it up in the air.

I bought the 28.5 foot Max Gains Systems mast which is similar to the DX Engineering several years ago, but the prices have increased dramatically over the past year or so. I chose the 28.5 foot HD mast because I can reach the top without using a ladder, and I didn't want to have to lug a ladder around in my car. For using 2 meter simplex and repeaters, and for HF inverted V antennas, its be adequate. 73 KD5YOU

If this will be used for more than an occassional set-up, the fiberglass poles should be painted to prevent UV damage. It is unbelievable how quickly fiberglass will start to delaminate from UV exposure and start growing "hairs" that will make the mast very uncomfortable and irrating to handle.
