Re: End Fed Half Wave setup

Ryan,
I must run a stealth antenna at my QTH. The transformer is at the peak of my house at 20 about feet with the antenna wire 26 gauge out to some trees, no ground or counterpoise other than the coax lead in. about 67 feet of wire gives me 40, 20, 15 and 10 meters without a tuner and 30, 18 and 12 meters with a tuner. It is not optimum but I make contacts with it using QRP power. The higher the better for the antenna wire but you use what you have. Let me know if you find a better solution and let me know if you need help? I can help you build one if you want.

Let me know if you find a better solution. I am always looking for a better stealth antenna.

73,

Thank you everyone for the additional detail.

The reason for my question is that this is one solution I'm thinking about to get an HF antenna into my shack. My "shack" is upstairs in a bedroom and my 2/70 antenna is up in the attic. I've already run coax from the attic to the room. With that already in place the "easy" way to get an HF antenna run is to put the transformer/feed in the attic and attach to existing coax. Then drop the wire out of an attic vent to my fence and run the whatever additional feet is required along the wooden fence based upon whatever length / band(s) antenna I decide to go with. But I've not run into another example of the feed line being at the high point. Before I invested into this experiment I thought I'm ask the collective minds here.

So far I've not found that this will not work but it's obviously an additional comprise like every antenna. I will check out the FB group and continue to research. Still on the fence (pun intended) on if it's worth going forward with this design or scrapping it and finding another solution. Research never ends.

If I do decide to go forward with this idea I'm looking at ants from myantennas.com and chameleon.com. Not cheap stuff but then I don't have to do any of the math. I'll also e-mail them after I do more research. Again, appreciate the collective knowledge!
