Hybrid set-up
  • Having trouble adding pics to site...? my computer incompetence. Feel free to use these pics anyway that you want.
    This is my V1 with whip ( 96" fiberglass) Hybrid base. It is attached with angle iron to the eave of my roof at 14 foot from the ground and and extending out about 2.5 foot from the gutter. The Hybrid base is attched to the angle-iron by the ground bolt on bottom, which is also attached to a small flattened piece of 1" copper (3 inches long) acting as a ground plate. To this is attached a bare 10 gauge copper wire ground wire enclosed in a 1.5 inch pvc pipe, (to add support to angle iron as well) that is attached to cemented ground support and the copper wire terminates in a buried 8 foot ground rod. The copper plate above is attached to 4 counterpoises 25 foot long 16 gauge wire (most economical size to buy at Home Depot) which are in a 180 degree configuration ( as it is close to the edge of my property). The pvc pole is painted camoflauge green/tan. Ugly balun about 18 foot of coax.

  • Nice set up David, and nice QRZ.com page.  My Hybrid with 99' random wire over the roof works well.  I was beginning to think it was a pretty dead set of bands the last couple of days when 10 meters opened this afternoon to New Zealand (ZL1ALZ - about 7550 miles) and Australia (VK2GW - a bit over 8900 miles) on 12 meters from Ft Collins CO.  Tomorrow I head for the mountains to teach my map reading/oreinteering class,but will be free in the afternoon and overnight until the next morning for their practical. If the weather clears a bit of t-storms I hope to try to get a line into a tall Pondersoa pine tree and put a 66' vertical up in the air, and use the Hybrid with it as the base tomorrow afternoon and night.  If it happens I'll send a post with results.
  • We finished the training mentioned above at dusk and so needed to do the set up mostly in the dark - but the Hybrid is  very easy to set up in a portable situation. A cold front moved through during the day and we were still experiencing 35 mph winds, gusts to 50, sleet squalls, and low temp - pulled into camp at 25 degrees and didn't get any warmer through the night - HI.  The place where this was set up was NW of Fort Collins close to the WY border and is around 8300' in elevation where we were. It is the Upper Unit of the Cheorkee Park State Wildlife Area. In any event, I did not do the 66' vertical, didn't think I could find my line in the dark, and the winds would have made shooting a line over a tree tricky.  So I made an inverted "L" with the Hybrid at the bottom of the vertical section.  Took the 66' flex weave wire up about 31' on a Jackite Pole, and then did the balance of about 35' of wire to another Jackite Pole (horizontal wire was about 30' above the ground).  The horizontal part ran N and S south.  I used the 25' radials included in one of my Chameleon kits - can't remember which - but simply put them on the bottom lug of the Hybrid and then screwed the Hybrid onto the Jaw Mount, which was attached to a tripod with legs spread out on the ground.  Anyway, pictures follow - not pretty but was pretty worn out by the day's hike in the elements and trying to install the system in the dark.  The pics at daylight are at dawn the next morning.  Operated off and on during the night.  As the cold front pushed east, it produced large static crashes and condx did not improve much in that regard until about 3 or 4 AM the next morning.  Anyway, made QSO's with France, a couple with Japan, Saint Barthelomy, French Polynesia, and Cuba.  Had a VK that just could not pull the "T" in my callsign although he really tried hard.  But, close counts in horsehoes and grenades, not QSO's.  I did a couple of Reverse Beacon CQ's and was heard by DX rcvrs in New Zealand and Canada- QC, but also the following states: MD, PA, OH, NC, VA, GA, MA, NV, CO. 

    Here are the pictures:

    View from the far Jackite Pole looking back to the truck.  You can see the white ground mount of the Jackite Pole closes to the truck and the Hybrid is at its base.

    Close Jackite Pole with flex weave wire attached to the Hybrid and running 31' up to the top, where it runs horizontally to the far Jackite Pole to the south.

    TS-480SAT, LDG tuner, Palm mini paddle/key, and that is not a bit past 2:30 in the afternoon on the truck clock - HI.

    Hybrid connections with sun starting to come up.

    I think you can see both poles (this was a tough shot in the trees) in this dawn shot.  The Hybrid is at the base of the black pole closest to the truck, runs vertically to the top and then the balance of the 66' wire runs to the white pole further away.

    Any great fun.  I think the Hybrid works great as an end fed - both in the field and at home.

  • I have just revised the roof strut. The angle iron in the previous pictures began to twist quite a bit, so I have replaced it with metal strut called SUPERSTRUT, which is found in the electrical section of Home Depot along side the conduit and ground rods. It is about $12 for a 10 foot section. I used 6.5 foot and painted it black, as can be seen. About 2.5 foot sticks out beyond the gutter.  The ground wire (10AWG copper)  is in the pvc conduit which gives "some" support and which goes down to the ground rod. A copper plate (flattened 1" copper pipe) connects the ground wire to base of hybrid and the 4 (25 foot) counterpoise wires are attached at the other end. The bottom section of the V1L has been wrapped in several layers of  green electrical tape to add "some" support, but mainly to camoflauge it, as I did not want to paint it. The ugly balun is attached to the strut. I used penetrox on all connections. The current set-up is now a V1L lower part with Hybrid base and CHA mil-whip and somewhere in the picture is the new Capacitance-hat.

  • Nice setup!

     

    How did you connect the SuperStrut to the pole?

  • Thanks. At the upper end of the pole I used a piece of a pvc coupler to strengthen the end, then drilled a thru' and thru hole and placed a heavy duty cable tie around the strut. You can easily see it in the second picture if you enlarge the pic.. The bottom end of the pole is attached to a piece of thicker pvc that I cemented in.
    Good luck,
    73's.
  • Added the Cap-Hat to my installation, which seems to make a difference(bit hard to quantify at this time). As has been reported in another thread, small branches can cause some havoc with the Cap-Hat and when I returned from my Colorado vacation, things were pretty twisted and bent from a number of storms that hit south Florida. The good news is once I released all it sprung back to normal - amazing the flexibility and strength of the antenna-spring ability. Below are pics of the antenna before re-intstallation.  I have wrapped the V1L base with a lot of tape to add strength especially near each end and to and to make it less visible. Also taped the joints of the Mil-Whip with tape and rubber compound. Makes it easier to see where it is in the tree! My green and black mamba (snake) which has been taking a nice "bite" out of the airwaves!
