Thanks. Ill read through it when I get home

Can I just use #4 battery cable for ground straps?

Still at it . Went as far as removing the paint from the antenna ( nice and shine silver). Tested the swr at the antenna. Still no luck. Best swr is 1.8-1.8 1/2. Made a brand new bottom shaft out of 3/4 copper tubing. ( threads at coil are 1/2x20). I going to play with ground straps on the...

Yes I spoke to Kale, and it was he who suggested to use RG8 over RG213. He also said not to worry about using 18'. He said to use just what I needed to get from point A to point B

I am going to hook up the swr meter at the antenna and see if there is any difference, I am also going to re check all my solder joints. I think I am going to cut my coax down to exactly the length I need instead of using the whole 18'. I think I can get away with as little as 12'. And I will...

Thanks for the explanation. So if I understand correctly. The RG213 is better shielded than the RG8/X that's why I'm seeing higher SWR's?

Lol. Interesting. Trying to absorbed as much as my little brain will allow . Lol

Thanks for all the help. I will do some more testing this weekend. Here is a picture of the coax I have bean using. I'm not sure which one is better , maybe some one can answer this. Thanks Tony

Thanks for chiming in. You lost me on bandwidth When I changed the coax from a 213 to a RG8 I was able to get the SWR's down from a 1.8 to a 1.4. The only difference is I just routed the RG8 around and threw the window Instead of running it under my truck and through the floor like the 213...

UPDATE . I spoke to Kale today. I am running 18' of RG213. He suggested to try RG8. So I took 18' feet of RG 8 and ran it along the out side of my truck and I was able to get my SWR's down to 1.4 across the band. So this weekend I will run the RG8 coax exactly how I have the RG213 run to...

Thanks. I think I will give him a call in the morning.

Thanks

Ok. I extended my shaft , just for grins. I didn't want to go out and buy a longer shaft before doing some testing. I got it above the roof about 10" The total length of the bottom shaft is 27". The whip is trimmed down to 36" This gave me the best SWR @ 1.8. So if I go out and buy a 27"...

How long was your whip alone and what where u able to get your SWR's down to?

How long was your whip when you where done tuning it. I mean total length when it's not mounted in the antenna. Thanks

How do I get ahold of Kale ?

I saw some where on the net. Where a guy made a shaft from a pice of copper tubbing. Will this work ? I mean just making the bottom shaft longer .

The 102 is mounted in the exact same place on the same bracket. SWR's are 1.1-1.3

I have contacted some one from a email address that was on my packaging when I purchased the predator . He has said the coil has to be 4" above the roof. My antenna has 2 coils still under the roof line .
