Inverted V made longer and now...

[n2ize]

I am seeming to get an odd antenna pattern. If you look up calls received by me on pskreporter, I appear to have created quite the deadzone for 20M. 40M, 30M, hell, even 10M seems to work reasonably well, but check out how it appears on 20:

So, I added about 15 ft to one leg, and 8 ft to another leg of the V (Due to yard size/shape, and feedpoint placement), so I understand I have a bit of a random-wire OCF going. Before the lengthening, I was getting reasonable performance on 40, great perf on 20, and nothing on 10M.

Is this just a fact of life with OCFs?

What band is the antenna optimized for ? What type of feed-line are you using ? What type of tuner ? For decades I used an inverted vee cut for 75-80 m. I fed it with open wire line and used a old style Johnson Matchbox (link coupling) and I got incredibly great performance on 80-20m. There was some "directionality" to it , I got better results North- South than East /West but that's the nature of the beast. But I always had a very respectable signal (to put it mildly) and even busted through a few pileups on the rare occaision when the DX-ing bug bit me. The feed point should be as high as you can get it (pref 60-70+ feet) and the ends should be 20 feet above ground level. Balanced line and a good tuner made a big difference. Coax and baluns degraded performance considerably.
