Re: End Fed antennas w/ uBITX #ubitx

Thin black wire is really hard to see.  I struggle to get the sun in just the right position to be able to shoot photographs of people can at least SEE my 3 antennas....  

300ohm window line is fairly  hard to see, also.  

I have made insulators from quarter inch plastic stiff tubes before.... left over from medical supplies. 

braided fishing line can be had up to 80 pounds strength, and it’s flat impossible to see, if you buy dark green.   I use bright orange to even have a prayer of finding it  after I shoot it over trees.

Run it to a balun at the back of your house. Instant near zero-loss center fed , off center-fed, whatever you want Antenna.

If you want vertical, run it along side the trunk of a good tree.   Or put in a really proud flagpole!

Jack,

It's unfortunate she had you take down that other antenna.
If it's high enough the neighbors won't even see it, especially on a cloudy day.

So, exactly what do you have in the way of a crappy EFHW, and what matching network?
Why is it crappy?
Then I'll know what not to do.

If you want stealth, that's a good way to go.
Some skinny wire, perhaps galvanized steel for strength, and a matchbox on the side of the house
are much harder to see than coax going up to the middle of a dipole.

I think everyone here knows that, when working QRP, the antenna system is a HUGE factor in one's success, or lack thereof. The good news: I'm fortunate in one manner, in that I am surrounded by 80' trees on almost 3 acres. The bad news: The XYL will not abide ANY antenna that is visible. She voted this one down:
 
My antenna situation poses a true dilemma (i.e., two choices, both bad), in that I really enjoy QRP work, but with my crappy EFHW, I really need more power to be effective. So, any time I see an antenna article that might even hint at being stealthy, I'm reading it. Indeed, I would like to see more posts about people who are successfully using their µBITX with stealthy antennas. When JackAl is done, a mag loop and controller are in my future.
