Sure I understand, I did not explain it properly. BTW, the link is interesting and perhaps the cheapo amp changed the shape for the worse given that's it's not omni.
I was driving around my block (the issues started around 5-10 seconds away from my home) where the sound (not signal or wave) was 100% to my ear before the repeater and amp was ever in use.
I was using my station on simplex with my family for the past year without issues with any nearby direction. Again, I was only a few blocks down the road when the signal was warped because of my noob experiment. The outcome is interesting, learned a lot by my own ignorance.
I ordered a cheap omni last night to see what happens and to keep it as a backup down the road. jpole was what I had for GMRS and it's clearly not intended for repeater use with an amp incorrectly used. My dual bander amateur worked great without the amp...but I need a quality tuned GMRS base antenna. I have parts to build one..but I don't want to , I just want to toss up a completed antenna without tuning it.
