321. [TowerTalk] DXE 8 element Circle array problem (score: 1)

My array is not working in the NE/SW directions. I found one of my cables had been chewed on by voles. I replaced it. No change. I checked all the cable to make sure that the center had not pulled ba

Update: First of all Thanks the the DXE and Rod for the extensive help. The problem appears to be located inside the main relay unit. L2 the RF Choke is discolored and starts to smoke with 12v applie

Walmart.com is trying to become Amazon with 3rd party vendors. More competition usually equates to better prices. I am good with that! However, one thing to watch is whether the item you're purchasin

After testing each active element I found two that were not working very well....not much amplification and one that is about 10db on my s meter too hot. The two that were low I found that the chassi

325. [TowerTalk] Cushcraft ma160v matching coil (score: 1)

Has anyone built their own coil for this antenna? With a lousy radial field you don't need a match. I installed a few more radials and now the swr has jumped and the bandwidth is tiny on this antenna

I think you misunderstood. I have the directions from Cushcraft. If you put this antenna under a better radial field you need a matching system. One option is a shunt coil. I used the DXE example as

I have a couple of these that appear to have lower output than the others. Has anyone fixed these in the field. Is there a common failure component? W0MU _____________________________________________

Yes, I repaired two that the F connector had been strong armed and twisted and I replaced those. They both have the proper jumper installed. Worth triple checking. Rick N6RK W0MU ____________________

Do you have a way to test your coax runs? Maybe critters have eaten part of a cable. I found this in my rcv array field where I have a huge Vole issue. On 11/28/2016 6:37 AM, jimlux wrote: On 11/27/1

We had the same thing happen in V47 on our 160/80 inverted V's. We would be cooking along and then boom the SWR would go up. Go outside in the dark and find the dipole end on the ground. I don't thin

I have read a number of places that radials that exceed the height of the antenna are not worth it. From what I understand more of whatever length you have for on ground or buried radial is better. I

In known rocky areas I have found that you should drive them in on an angle. It gives them a chance to deflect. I found driving them into soil filled with river rocks to be much easier when slanted.

The SteppIR DB-18 or 18E I think is what you would want. The only issue I have with SteppIR is you do not have instant band changes and you cannot share the antenna with a 2nd rig with a multiplexer.
