First off I have to say Thanks for all of the quick responses to help. Lot's of information for a new guy and not a lot of B.S. Thanks again ever so much. The results of a day spent on the roof with the antenna stretched out across the roof on a couple of plastic patio chairs. Don't know why...

lying on plastic patio chairs there is now a 1.2:1 swr across the board. But, the gamma rod is almost bottomed out and the dog bone is moved higher to where the end of the gamma rod is about the middle of the dog bone. But ive got swr

Bottom ring was not 17" changed that. All my radials are now 35.5" from spreader. Main radiator is now just under 29" have it laying down on a couple of plastic patio chairs stretched out across the top of the roof. Just getting ready to start checking and tweaking

reset the radials with the 35.5 to bottom of hoop. chose 30ft 1-9/32" for 27.205mhz, chl 20 on CB for 7/8 wave as starting point Gamma is not bottomed out, lots of room each way. moving the gamma dog bone up will do what? effect higher freq.? i presume lowering it would do the opposite. do...

i had those numbers also for the gamma dog bone. i measured bottom of ring to bottom of d.b. i basically had 36 5/8" my gamma for L2 was 25" my tip length, i was always going for total to try and match a wavelength at 7/8, 3/4, maybe i should try 5/8 if those don't work tomorrow. what...

I did reset my radials to the 35.5 that was in the manual although i measured to the top of the hoop so i will have to redo that tomorrow, it's dark now... feed point checks good. will recheck gamma also and start dropping the whip little by little. too bad i can't check it while it is...

marconi, just got home from work. you are right the screws were sheet metal but i replaced everything with SS and i put two additional screws on each side at the joints so now there are 4 at the joints. took down the antenna pulled the whip which is tubing (corrugated). the whip itself is 47 1/4...

Marconi, yes please ask your question

Marconi. Thank you very much. Those look like what I am needing. And I hear you about centering the Gamma between the radials. I have gone so far as to really straighten everything. Just like straightening arrows. The radial lengths have been a concern. 81.5" 90" shorter longer. Back in the day...

Marconi, I think you may be right. I was just doing some research and was coming to that conclusion also. I just remember years ago it actually worked very well.

I have been everywhere from 31'2" to 27'7" on the main radiator and 81.5" to 90" on the radials. If you have other lengths I can try I am open to anything.

That is what this is all about. I have been every where from 31'2"" down to 27'7"" on the main radiator and 81.5"" to 90" on the radials. If you have some other lengths for me to try they would be much appreciated.

Ok. Check at feed point and try a different power supply maybe. I got this antenna many years ago. Maybe it is not a Vector. It does have the four radials with the hoop but it is made out of (the best way to describe it) corrugated aluminum. No hat on the top of the whip and the whip is...

Yes, have even tried different jumpers. Something I just thought of since output of the radio might be low. I have modified a computer power supply to use but I notice it only puts out 12v dc and not 13.8v. maybe I am not getting full power out.

Coax is new grey, with foam rg8 does not seem to have any problems with it checking with an ohm meter. Can put the radio(s) in the truck and the meters also and everything works fine for all. Do I need to isolate the ant. from the mast? As I said earlier I have tried the stock settings for...

Brand new to the forum. Pulled out the old Vector 4000 after years in storage. Set it up to all of the old marks after cleaning it up and making sure all connections were good. Hooked it up to the meter. Got calibration on chnl 1 and swr of 1.1. Went to 23 and could not get a calibration...
