Need grounding help

[cecil]

On a mobile setup i recently put together, im getting 2.3 to 2.4 swr readings. My connects are tight, new coax and i grounded the stake mount to the side of my truck bed with a short run of 12 ga wire.
Im wondering if I could use a longer length of ground wire directly to the frame?

Sounds like you mounted a antenna in one of the stake holes right up next to the cab....

All the grounding in the world will not help you grasshopper....The antenna is just too close to the cab...

Move it to the roof, or to one of the back stake holes and then you will see SWR drop like a rock.

Listen to JJD he's the master......

Give us a little more info like the antenna’s brand, it’s length, where you mounted it, (JJD’s probably right on that), and anything else you did.

Yup, mounted near the cab. RG8x coax. Stake mount with a Wilson 5000. Used the 5” rod supplied from Wilson to the stud.
Galaxy 95T radio.
Thanks

if you put it on the roof you will never regret it, unless you go to the carwash or bang into carports,trees, or your wife don't like it ,,, otherwise it's the best omni-position on a pickup and you will gain range & reception

By using the 5” shaft the antenna now is 5” short, the short shaft is to accommodate a spring. Replace the 5” shaft with the longer one Or get a longer stinger (whip) and check the SWR again.

Ok, I’ll put the 10” on. I wondered why they supplied two of them. I also have to move the mount away from the cab...and get longer coax!! More parts to buy, but I’ll get it right.
Appreciate the help here!

I moved the antenna to a stake pocket in the back. Low SWR now. Thanks.
Maybe someday this grasshopper will sent a Soundwave from the sugar maples down to armadillo land!
