[TowerTalk] 160M Inverted Vee vs. Half Slopers

[Bill Fisher - W4AN]

Well the obvious answer is both.  But, if you are forced to make a 
decision... I would say the 1/2 sloper would be the best.  Now a word of 
caution:

It is my experience that a 1/2 sloper for 80 or 160 seems to only work 
under some kind of 40 meter yagi.  I had 1/2 slopers for 80 and 160 on a 
90' Rohn 45 with a TH7 and a 402CD on top.  They worked very well.  

I used 1/2 slopers at K4VX/0 many years ago that were mounted on a 130' 
tower with a full sized 3 element 40 meter yagi.  One NE and one west.  
They also worked very well.  On RX, there was about 10db difference 
between the two antennas on some signals.  

I have heard of others who only had a large tribander who have failed to 
even make the antenna resonant in the band.   

Try the 1/2 sloper first.  If you can get it resonant in the band, the 
chances are good that it will work FB.  If it doesn't, you know what to 
do.
