This thing looks really rugged. It's a pity they do not ship to Germany. 😐 Anyway - may I ask a ham newbie question? If so: When using such a dipole with that sort of bracket or something similar not outdoors, but on a balcony in 3rd floor, does it then require any sort of grounding? I assume not ... 🤔 (I am talking about a temporary setup that is not supposed to stay outside in lightning/thundstorm.)

We made an air launcher for paper rockets that we took to preschools for years. I was trying to figure out how to adapt the concept to make a line launcher for radio antennas (now that I'm a ham). This is it. I don't need to reinvent the wheel, just watch the video. 😊

@hamradiowithkevin
@hamradiowithkevin 2 дня назад
It should not matter the thickness really, look for thicknesses that will not flop around as much. A hobby store with music wire is what you want to check out. You can hold the different thicknesses to pick the kind you want for your build. Hope that helps. 73

Dear K7SW. Good afternoon. May I have one question? When you built this antenna you don't use tunner or ballon for this project? So do you use the simple raw inverted V-dipole antenna? In advance thanks for your reply.
@hamradiowithkevin
@hamradiowithkevin 4 дня назад
Yes, you are correct. The idea is to be simple and easy to use. Could you add all that you have described, most certainly. Just know that you will indeed make contacts and be able to use this antenna. Great question you had

Have you tried 40m dipole configuration with hamsticks, 6’ off the ground as a NVIS antenna? Would be a fast setup for an emergency, especially from a home station.

Why not just run coax all the way and use the remote tuner on the mast at the antenna? Why make the ladder line part of your antenna at all?
@hamradiowithkevin
@hamradiowithkevin 4 дня назад
This specific antenna was made and designed for the 4:1 balun. And for the contest I did not want to make that change on short notice. Also it would be too much wieght at the top of that mast.
@kd8opi
@kd8opi 4 дня назад
@@hamradiowithkevin I get it, but still. The great thing about a remote tuner is that it only “sees” the antenna, you don’t want it matching the feed line. You want that remote unit right on top of the antenna with little to no feed line. Though I totally understand not changing your set up right now before a contest.

I live in a 31 foot Colman trailer and I camp host in an rv park in California at the moment. I am not a ham radio operator yet but I do like to listen to the bands on an Icom radio I currently use a 102 inch whip as my antenna in a 10 foot fence post and a tripod. It takes a lot of work to listen to most bands and I’m sure I’m missing a lot. Would this be a better option?
@hamradiowithkevin
@hamradiowithkevin 7 дней назад
Tough call, being in an RV park you have restrictions. many people dislike like antennas. Your vertical antenna will be more suited for your location. If you can make the antenna longer that would be better for your listening enjoyment.
@terryshackelford712

Interesting I wonder is a 12 ga thhn wire would be even louder? It seem like it would be tougher, & if you doing a drive up & set up activation the heavier weight probably wouldn't matter as much.

@thebnbaldwin

I replaced my LDG AT100PROII with the URT-1 and doubled the power I can use on digital. And, since the match is achieved at the antenna, I have maximum transfer of power. It's not just fooling the transmitter, thinking it has a good match, and struggling with all the reflected power on the feedline. It does take a little getting used pushing the tune button when you change bands or make big frequency changes within the band. Carl has a winner with the URT-1 !

This tuner does look interesting. As a no code tech, looking to finally upgrade to general, im now considering something like this to add to the shack. My questions to you is: is it reasonably affordable, and also the smaller yellow unit you had shown price comparison, and would the smaller unit be capable to go upto 6m, or higher, because i like to build antennas, so i could verify everything. Thanks, and 73s, John, N8SGM.

I’ve been running the LDG RT100 which is very similar. My Yaesu ATAS radios send the bias power over coax so I don’t need the control head. I wonder if the URT1 is similar.

No… at least not today. I use an EFHW that’s resonant on 40, 20, 15 and 10. I work qrp only from my QTH. For 17 and 12 I use a vertical radio wire right outside my second story window with only 3 ft of coax as feedline going into the small Elecraft qrp tuner. But, that tuner would be killer on a non-resonant sky-loop.

@hamradiowithkevin
@hamradiowithkevin Месяц назад
No, done antenna are designed to be on the ground, and others are designed to be in the air. If your new to radio, keep this in mind, if you can make contacts with your setup it is a win. To me, the only wrong way is to not put up an antenna at all. Can some antennas work better than others? Absolutely, do most all antennas work? You bet. Keep setting up and having fun. You will learn more everytime. 73

Nice video. Folks may consider a DIY battery. I just built a 105 AH LiFePO4 battery. The 4 prismatic cells just nicely fit in a U1 battery box. I used a JBD-SP04S020 4S 120A LiFePO4 BMS which has low temperature cut off and is controlled via Bluetooth app. I had the BMS left over from a previous 560AH battery build for my sailboat, but new would cost $60. Alternatively, one could get a basic BMS for about $12. In the end, the 105AH battery cost me $115 for the cells plus $12 for a NOCO U1 battery box. Looks and works great. I can send phots if interested.
