Ham Radio: SLOPER ANTENNA - POSITIVES & NEGATIVES

From Colorado, using an EFHW sloper fed a few feet off the ground, with a 25 ft. mast on the high end, I'm able to get to Europe, Mexico, Canada, and South America with 80 watts.

Great video Tim, spot on with what I've experienced with my sloping backyard antennas in Poland and the very reason I experimented with the L shape. I was trying to lower my takeoff angle with an EFHW. As you know I love your antenna modelling and theory videos. keep them coming my friend!!

Great Tim! Your videos are a treasure.

Was interesting Tim, thanks for that,..cheers n happy new year!

Endfed LW is pretty much the only antena I use so this video is beyond interessting for me. Thnx !

I liked this one, I typically run a 20m long efhw in an Inv portable. Thanks Tim.

Great info. Thank you

Great video Tim, nice sound quality. 😊

Thanks Tim!

Good stuff! Happy New Year.. 73 Leo.

Well done Tim. Interesting video. I never use my endfed as a sloper, always as an inverted V. Best 73 and Happy New Year de ON4MGY Nic

Great Video Tim. Big improvement in the audio quality too!👍

Nice video Tim ... I live on a 7th floor and my antenna is a steel wire with 21 +/- meters of 0.8mm ... take off angle is about 65º above ground 3.5 meters I work 80, 40, 20, 15 and 10 meters with very good reports Happy Near Year - CR7BDO / 73

Very interesting Tim - being a PoTA guy running QRP I've had a end-fed 40m antenna in my collection for a while, the trouble is that the magloop is so easy to setup ! I have a PoTA activation planned for 2/1/23, will see how the weather is and if I can get the 40m end fed up in the New Forest :)

Great video Tim! Should really look into MMANA to get a feeling which way of zigzag-ing my EFHW down and into the small garden might work best.

Thas is interesting Tim. My end fed at home is a sloper, facing south, just because that's the only way it fits! It is relatively flat though. I wonder if you ever model antennas against different ground types? There is a theory that we get away with low masts on rocky mountain tops because the real RF ground can be several metres below the surface layer of shattered rock.

I have an end fed random wire that I use at my home in a portable configuration. That’s to say I zip tie the insulator to the top of a DX commander 10 meter pole and slope downwards… not exactly sure of the angle, but the top is facing hue south, and I was able to get into Europe (uk, Northern Ireland, Italy, Belgium, and even into Southern Africa ) with 100 watts from the east coast of the US…. One thing I can’t do for some reason is get into the west coast of the US so far. Internal ATU in my FT450D tunes all bands 80 thru 6

Did i miss something? What about if its fed from the top? Is it all the same? Thank you for the video!

right thats the experiment of the day sorted for next beach day. Ill try feed point at waters edge and walk back up with the pole.

I’m setting up a stealth antenna at my QTH and this video was incredibly helpful. Showed that in my situation, I need to attach the high end of the sloper lower than I initially thought so that I would have a more omnidirectional antenna. That said, would there be a substantial difference in radiation pattern if the antenna feedpoint was mounted say 3m off the deck?
