Rowlands reflector question

Jackson Beard

I just ordered the commercial version.  I'll post results as soon as I get them.

There is also a Facebook page "End Fed Half Wave Antenna".  Once you join look in the files section.   The one page direction can be viewed in the link to the YouTube video.   I can send the file once I get home today from the cabin where some of my family are hanging out from the virus. Dan

Where would I get the build directions?Thanks,Rowland

I just made one for our cabin on lake Wenatchee but you are welcome to give it a try.  It is made to handle up to 500 watts.  I have wire and the transformer, you just need coax.
Just yesterday on a low elevation SOTA summit I worked coast to coast and VA to CA and MI to TX with 5 watts and 599 reports using my EFHW antenna.  Fun day away from virus carriers.

I’d be inclined to put up a 135’ long OCFD if you have the space.  I like the Buckmaster one because it’s pretty bomb-proof but it’s not magically better than all the other variants performance wise.

As mentioned there are several options.  The easiest would be an end fed zep. Not the best option but will work.  I have used one on several occasions in the field and had good success. Get one end up in the tree and use it as a sloper.  Next would be an OCFD get the middle in the tree and the two ends spead out and connected so they are ~10&#39; off of the ground.  Paul may have other thoughts on this.

Probably 30 feet high max.

What bands do you want to cover?  And how high can you easily get an antenna (trees, etc)?

How much do you want to spend? There are G5RVs, Off center fed dipoles, end feed zeps, certified and so on

Since everyone is offering antenna advice, I have a perfect condition kenwood hf radio I should use this time to get working. 
What&#39;s the easiest antenna to get put u pl in short order?

Paul,  This is clearly a  newbie question…but  I’m curious, what happens if the inverted V is an actual V? Where the  ends at 30 Ft and center is at 6ft?

Rowland asked if adding a reflector below his 80m OCFD would improve NVIS performance on 80m.
Error! Filename not specified.
A bit more than a 2dBi improvement at 90 degrees.  That’s with the reflector length optimized for gain.  The modeled reflector height was .1m AGL.
The downside is that it messes up SWR somewhat.  I didn’t snap a comparison though, there are just too many installation variables to make the results meaningful.
