Getting ready for HF moble

[J Sierra]

Got the antenna mount on. The antenna is a Comet H-422 HF. The mount has a pivot at the bottom and the tube tilts down to put the mast/antenna up. The mast is 3 sections and the antenna goes up/ down in 5 min and all fits in the bed of the Jeep. This is for camping/ mountain top HF operation.

Hats off to you sir ... That is actually very cool ...

My, that's a big one. I have a similar fold over trailer hitch mast mount from a guy on Ebay. I use it a lot with surplus 5ft military mast sections. Its nice to be able to use large base station type antennas when camping.

Nice set up, will you be participating in Field Day?

 

[J Sierra]

Yes I will, making all the cords and cables I need the operate on field day. I have a Yaesu MP 1000 that has a defective A/C power supply so only works on 12V so it is going mobile. I was testing the antenna last night, it works good on 40 meters. Works better on 20 meters. Tonight I am going to test the radio in the bed of the Jeep to make sure it all works.

Whip and AH-4 tuner testing in my driveway.

My only comment I have is not a positive one. Raising the feedpoint of a vertical that far above a ground plane introduces massive losses and although the tuner will probably achieve a good match, the efficiency of this antenna system will be very poor. You want the antenna feed point, or the output of the auto tuner as close to a large hunk of metal as you can get. Sticking it up in the air or on a trailer hitch, etc, is to be avoided.
