Where did you get that ground plane kit ? A99 radials are usually 4. See picture. I am just curious.

Ok. With a half wave length coax taking into consideration velocity factor. Thanks.

How you calculate that ?

What I want to know if the stretched ( around 117 inches ) whips would be detrimental to the signal . I think I will be the only one using a whip. The other competitors will be using center loaded antennas like Predator 10k, Monkey made, and other center loaded ones. Since my antenna will be...

What do those readings tell you? Remember, I will run only 800 to 1,000 watts for this competition. After that, I will run the driver at around 200 watt with a center loaded Stryker SR-A10 antenna

I can add a half inch ( about 1 feet long ) strap to the rear hinge. Will it resolve the ground looses ? I tested them with the ground strap as well with no noticeable differences. The three magnets have aluminum foil to improve capacitive ground.

And the last reading from the aluminum whip on channel 7 I was wondering something. Since these antennas are longer than they are supposed to be, ( probably because they are not on the center of the roof ) Will they perform the same, better or worse than a 108 inches long whip ? The idea...

Hi again. This is an update. I bought a 3 magnet mount to replace the 1 magnet mount in order to achieve more surface area. Also, I moved it 1 foot towards the center of the roof. I upgraded the coax with RG-400 ( Belden 84142 ). It improved the SWR. Since I move it, I had to cut 1 inch from...

Bu the way, why the length of this whip mounted on the rear is way longer than 108 “( in my case 117 inches long ) ? Is it because of the position ?

Probably, it will. Noise on the dipole will be less.

I am using a spring because a 102 whip is too short. It should be around 108” long for 11 meters. The spring will add the length required.

Brandon, the whip tunes to 1.1 on the middle of the roof. I know for sure that’s the better spot for any antenna. I just want to take advantage of the directivity of the whip mounted on the rear. And for sure, the counterpoise looks extremely ridiculous. Isn’t it to achieve the goal to get...

Any idea why I could lowered the SWR to 1.0 with the radial compared with 1.3 with the rear gate opened? What’s involved here ?

Hi again brandon. Here are some other pictures with a radial attached to the ground strap. I could get a 1.0 SWR. The radial is 99” long. SS whip is 117” long.

Here some other pictures of the Mini1300 analyzer and the SS whip with 15” extensions ( adapter + 10” shaft + spring) mounted on the rear of the roof. I have to lift the rear gate to keep SWR controlled around 1.3 If not, SWR get close to 2.0.

brandon here are some pictures of the magnet mount. I could make a set of calibration loads out of common PL-259 ends to screw them on the SO-239 connector of the magnet mount. One shorted, one with a 50 ohm resistor.Is the open one really necessary with this mount ?

Brandon , I try to answer in order: 1- I attached the ground strap inside the magnet mount, where the shield is attached. I didn’t peel the foil off. ( see picture ) 2- I put my antenna on the rear of the roof because in theory it makes my antenna a bit more directional in that location, thus...

Here are some pictures of the analizer results with the rear gate opened ( I forgot to take a picture of gate opened ) First picture is with the gate opened and with the meter and amplifier in line. Second one is only cable and antenna and gate opened. The third one is with the gate closed with...

brandon, I’ll post some pictures in a couple of days. I have a Mini 1300 analyzer. Thanks for responding.

Yes I do
