I just made a clone of the cooltech gate mount using 1/8" x 1-1/4" aluminum bar stock. It's not as stiff as I'd like, so I'll probably have a gusset welded on. But I kind of don't want to mess with it.
My swr is 1:1 just about flat from a few below 1 and just starts going up a few past 40.

Currently using 4' k40 top loaded whip, but it won't clear the garage, so I'm going to have to switch to a 3' fire stick.

Pics to come.

 

post pics I'd love to see what you came up with. Perfect timing to as I'm in the market for a new mount, so making it would be up my alley if it looks good enough.

 

Ask and you shall receive!



I think if I remove one of the shim washers at the top it will cut down on the flex, but I drove it the way it is and it didn't bang on the top at all.


I added another "L" to cut down on the flexing, but like I said above, I think if I remove a washer I won't need it.


Materials used:

1- 3' length of 1/8" x 1-1/4" flat aluminum bar stock (you really onlyu need 9-10", so you have room to experiment) - about $7
8 - I used a mix of 1/4" and 5/16" because I wasn't sure what size would fit over the stock bolts. - under $1
1- 3/8" SO-239 stud that I had laying around - Around $5 on shipped on ebay, probably $10 at a truck stop

If I remake another one I'll probably make it shorter so the 90* is just above the top bolt like the cooltech, as it sits with a 4' antenna it's 91", I need to come down about 13" to clear my garage door lol

 

Also if you can find 1/4" bar stock it'd be a lot sturdier too, but none of the big box stores carry it around here.

 

looks good bro i think i'll give this a shot this weekend.

 

Aight man used your DIY instructions and I must say turned out really nice!!! Only set my back $7 compared to the insane prices being charged for mounts. I'll post pics later!!

 

Hey that mount looks great, of you didn't tell us we'd definitely think it was manufactured not DIY fab

Was it hard to bend the stock at the 90?
