I have a 102" CB antenna mounted on a home made stake pocket mount, This is made from 2" x 1-1/2" Tubing, It fits very snug inside the pocket, I also ran a bolt from the bead to the mount to ensure proper grounding. The match is 1.4 at 26.965 and 27.405 but if I lengthen the antenna it drops 1.2 if I add 4 inches to the antenna on 26.965 but 1.4 still at 27.405. Is this a lack of ground? I know that the proper length is 103.6" but I'm adding 4" with a 1/2" Aluminum spacer. What is really going on here. Side note, a fire stick 4' has a flat match. but I rather use the 102" whip Forgive me, but this is regarding a CB antenna. I know most people hate the cb band but can we stay on topic, keep it professional what I am asking is just regarding the match.

It's funny, I hear several women on the ham radio bands on my way home from work on my scanner. They sounded fairly intelligent to me. I would guess they tend to stray away from men who think in neanderthal ways. I know when a woman would key up on the cb half the town would key up and the trash they would begin to talk, So maybe thats one reason women stray or are selective in using ham radio.

Citizens Band, anyone?
Oh god no, please no, I do not need the ignorant conversations that appear on there. The Some or most of the CB users are extremely barbaric/prehistoric, Me radio stronger than yours, Squash. Me channel master you do as i say, 15 channels of bleed over. No thank you sir. I pass. I also hope that was not an attack on my intelligence.

All good answers thank you very much.
My reasons for asking these is GMRS seems to be my only option at this time, I have done a lot of studying, even doing pretests, studding the Q/A pool and when I do a pretest still get mid 60% and with a GMRS license is 80$ per person
I have a family member that is 35 miles away and we would love to use the radio for back and forth communications and also when we are off roading. on our ATV's
I would love to obtain my ham license but it appears it was not meant for me.

I know you said they don't want to but what I have learned when it comes to WiFi vs hardline, Always hardline it. WiFi has a bandwidth limit. The bandwidth on WiFi is shared bandwidth some routers are 480mbps vs hardline that is 10/100/1000mbps dedicated per line. At one shop we have 3 computers on the WiFi and they can see the lag vs the users on the hardline.
Just my thoughts

So far we ended up with a 0gain omni directional antenna, our HT's are able to communicate back to base that is 2miles away from inside the second building, there is minor static depending on how warm the weather gets but it works very well.

I wish it was a short burst, but its not, its the whole time they are keyed down. I will attempt to get a recording of it. if not I can simulate it with adobe audition, its like a rolling square wave constantly over the single,

I will post the exact frequency in a little while when I get in my truck, its int he 460mhz range so I know its not wifi or baby moniters. this happens over long distances of 30+ miles. You do present something that i am trying to figure out, maybe something that's a multifunction radio and the proper receiver may break the two signals into there respective uses, One being analog audio and one being maybe a laptop with GPS data
