ive got a 102 whip with spring on a tripod for temp use and i cant get the swr below a 3 till it rains then it drops to a 2.5 ive tried grounding it to a ground rod and no change even tried a jumper wire to a trampoline and it didnt change a thing !!!!!!
Still looking for a new tower for my new place but i cant go over 30 foot cause of the size of the yard and where i have to put it up at !!!!

Jason,
where is your tripod sitting,on the ground or roof?Try stringing 3-9' wires from the mount as ground radials.

Had a whip do that once. The insulator bushing was cracked and the whip was shorted.

as i raisd it higher the swr went down
also the wattage on my meter went down
from the begenning the swr's were about 1.3-1
wattage went from dk 15 on my galaxy 99 to 7 watt dk just by raising the antenna strange... |

Your wattmeter is not accurate.

If you can check your coax and any fitted plugs for shorts and breaks with a multimeter as it only takes a couple of tiny strands of the outer braid touching the centre core of the coax to mess the whole thing up, I spent a day looking for a problem on my coax and plugs and eventually found a patch lead with perfectly fitted plugs but when bent a certain way it presented a full short due to a break in the inner conductor shielding, very anoying and now in the trash minus the PL259 plugs.
good luck.

I have had bad springs do that. I just tinned some braided copper strap and attached it to both ends of the spring. Worked good, |
