High Static Level On 20 and 17 Meters Using Hygain	Reply

Anyone else using this antenna have this problem? The other bands seem to be fine. I believe I have the antenna properly grounded. Anyone have any suggestions as to what else I should check?

It's the AV-620.

are you getting noise with wind movement. there is a compound you can use to make better conductivity between elements , its like a grey silicon or something.. I think it come with the TA33 jr. conductive paste for aluminum. makes the joints between the elements electrically quiet.

The compound is called "Penetrox" and you can buy it at most of the electronic parts houses or amateur supply outfits. I use it on all of the joints on my aluminum verticals and yagis and it assures good ohmic bonding between the pieces. I paid around $15.00 for a large tube of the stuff which should last you through many antenna projects. Good DX! Mike

K5DXR, What does the noise sound like?? There are a million different causes for noise, but before anyone should offer a solution you better describe the noise in as much detail as you can. 73 Tom

One naturally occurring noise peak appears at approximately 18 Mhz, but varies up and down depending on location and time. Secondly, vertically polarized antennas are more prone to noise reception than horizonally polarized antennas. This said, you may have a near-by source causing you undue noise on those bands. Searching for such sources is a topic covered in several of the ARRL publications. Alan, KØBG

I tend to agree with Allan. Noise you are experience may not be the antenna itself , but rather from another source. I would suggest you first start by trying to eliminate the possibility it is coming from your own home. Once I tracked down noise that was coming from a defective electrical plug. To confirm & isolate the cause, I shut off each electrical circuit one at a time on the electrical panel in my home. When I reached a particular circuit, the noise on the radio suddenly disappeared. I determined what part of the house and what electrical circuits did not work in my house as it may be any one of these things attached to the circuit. I first suspected a large L.E.D. bedside alarm clock to be the cause, but I turned on the power, unplugged the clock and the noise source remained. As it turns out contacts in a bathroom G.F.I electrical plug was the cause. I changed the G.F.I. receptacle and no longer have the noise here. A handheld transistor radio tuned to an AM radio frequency where no stations exist will help reveal noise sources when the radio comes into close proximity with noise sources. Check your own home for similar possible sources of noise using the information I have supplied and good luck! 73 Charles - KC8VWM

GFIC type outlets can introduce noise into HF recivers. The Cheap ones can fail during HF transmissions! If your Station Ground is poor GFICs can cause strange Problems on HF! BEEN THERE DONE THAT! The Offending GFIC dos'nt even have to be on the same circuit as your station. Just sharing the same bad grounding System! The average $7.00 Model is not a good Choice if your a ham. the $15.00 top of the line model has much better filtering. But the best solution is proper RF and DC Grounding. Wait till the new AFIC (Arc Fault Interupter Circuit) Becomes more Common. You May see different QRM and Problems>
