Comparison of Trenton Military on 15034 khz on three different radios. Testing MLA 30 Plus, 80 ft long wire, and a 3 ft wire attached to my aluminum gutter.
There may also be a lack of continuity between sections of gutter. A typical installation may leave you counting on screws that pass through overlapping lengths of gutter.
@@SWLSignals23-hp6vp also, if you really want to see if the gutter works then do the test from right there. Try it, then pull the wire off the gutter to see if signal changes. You might just be gettin the signal boost from the white wire alone
I just did another test, wire taken off the gutter, wrapped around the telescopic antenna, then back on the gutter. I just posted another video with the results. Thank you for the suggestion. Have a great day!
I would use coax cable to reduce noise. Having a wire (antenna) partially indoors is noisy due to all kinds of noise from electronics. The shield should be connected to a counter poise. Can be a wire, a ground rod or some metallic object. At the radio both the antenna and the shield should be terminated.
Nice test, thanks for sharing. The gutter does work and it may be better than nothing however in this test, certainly seems 'clear' to me the MLA sounded best with the 80' wire a close second.
Thank you for the reply. I would agree, the MLA30+ is outperforming the other two. I like to experiment with different antenna types. I plan on doing some more tests with different wire set-ups. Horizontal vs. vertical, long vs. short, etc. Would you have ideas on any different tests?
@@SWLSignals23-hp6vp I am using an Alpha Antenna HOABuster, effectively a 9:1 UNun and my Condo gutter for my Ham HF antenna. Works great except I have to tackle some TVI. I work NA and Europe using my old Drake TR7 transceiver at 120 watts.
Yep, I was impressed with the results. There are quite a few videos on TH-cam on how to use a gutter as an antenna. I didn't use any coax on mine; since I didn't have any, but the results were acceptable. I would be interested in your results!
Try scraping some paint around the gutter screw to improve the connection with the bare wire

Never thought of that, thank you. Good tip!

I will give that a shot to see if any changes are noticeable. Thanks!

I will look into this as well! Thank you for the advise.
A good experiment, very interesting.
Thank you! Cheers!
WOW! Guess what I'm doing tomorrow 🤪
I'd been interested in your results!

It would be interesting to add an appropriate balun between the antenna and the feed line.
I don't have one, would you be able to recommend one? Thank you.
@@SWLSignals23-hp6vp I think you would want to use a 9:1 balun (or unun), basically treating the gutter as a long wire antenna.
@@FlyGuy2000perfect thank you.

Awesome innovation I reckon .. would love to try this with my whole zinc-alume roof lol :)
You should! I would like to know your results.
@@SWLSignals23-hp6vp give me some time and I will post something :)
You may want to make sure your wire is contacting bare metal on the rain drain....not paint for a better connection.
Yep, you are correct. I'll have to scrape some paint off, thank you for the tip!
I will try this. Thnx ;)

You may want to consider the effects of a lightning strike on your house. I think bad things may result if there is no fusible link.
I don't plan on keeping it, this was only for testing.
TECSUN喇叭的声音发闷，和我的pl600一样
A little bit yes, but overall I like the audio.
I had tv coax surrounding my house but it was so long that it really just picked up noise
I saw another video of a gutter antenna using a coax feed line. I want to try that to see if it improves the signal any.
Disregard my previous comment 🙂
No problem! Have a great day!
