    102" whip vs the rest

    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...

    102" whip vs the rest

    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...

    102" whip vs the rest

    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 ?

    1/2 wave Vs 5/8 wave vertical for DX?

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

    Mobile 102 Inch Whip w/spring

    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.

    102" whip vs the rest

    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...

    102" whip vs the rest

    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 ?

    102" whip vs the rest

    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.

    102" whip vs the rest

    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.

    102" whip vs the rest

    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 ?

    102" whip vs the rest

    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...

    102" whip vs the rest

    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...

    President HR2510 distorted RX audio

    By the way, Is this a first generation HR2510 ? A modification was made by the previous owner. Do you have any idea of the modification ? See pictures.
