My question is why do the other 2 antennas give me so much noise and the windom does not ?
P.S. Sometimes, not as often as i would like, the 9 s units of noise is not there.

Are you running any odd wall warts with the Kenwood by chance or move it close to say a USB hub on your comuputer? Are you sure it's actually the antenna(s) causing the noise? Lost more questions than answers...sorry.

Try to pick up a nice clean earth from the closest metal water pipe that heads off into the ground that also preferably doesn't have a bonding connection to the buildings MEN earth cable running back into the buildings mains power earthing.
Even an old piece of galvanized iron or copper water pipe hammered 4ft or so into the ground would be a good enough earth for a test to see what effect it has.
If that fixes it a single stainless steel earthing rod (2 rods will be needed most likely if you have sandy soil) with a 16mm earth cable back to the radio with a proper earth clamp at the rod end and a decent eyelet connector at the radio end should be the fix.
If that's still no better - If you have any lightning protection at the mast - try temporarily disconnecting that to see if it has any effect (Possible corrosion in the lightning arrestor , corrosion / LIR in the plugs or sockets , blown arrestor from a lightning strike and/or poor earth (Even foreign earth relative to the earth reference at the radio) at the arrestor.
Try temporarily hard earthing the mast from the same hard earthing point as before (Even try this if the antenna is a supposedly "Ground independent" variety)
Try also powering the equipment off a battery only - even a low current gel cell for a short RX only noise test - noise could be traveling back thru the mains supply , building cabling and/or internally generated within a power supply.
