Other stuff
- I use the Heil Pro Set Elite both at home as well as portable (keeps the hands free for logging).
- When portable I use LiPo and LiFePo batteries (8). They give you a lot of power at low weight. LiPo's are for the FT-817nd (I use 3S 2200mAh) and LiFePo's for the FT-857d (I use 4S 8700mAh). The FT-817nd shuts down at a lower voltage level. Therefore the 3S LiPo suffice.
- For getting antenna's up in a tree I use a slingshot with fish line reel by EZ Hang.
Pictures / details
1. Hy End Fed - half wave end fed "dipole" - made by PA3RK and PA3EKE - I have made a number of half wave wires for different
bands to go with the HyEndFed so I can work all bands from 6 to 80m with
it.
Hy End Fed antenna - great performer, easy to use portable |
3. DX-UHV mobile antenna, magnet mounted on my car
A good performer as far as mobile antennas go. The antenna is tuned using different coils that can be screwed into the top of the antenna. The antenna can hold two coils at the same time, allowing one to operate on two bands without changing the antenna.
4. AlexLoop Walkham, portable magnetic loop for 7-30Mhz

6. Hexbeam, multi-band 2 element

7. C-Pole, 40m wire antenna
C-Pole on 17m fiberglass pole |
When working portable there is not always space to set up an inverted V. For this reason I constructed a C-Pole for 40m. The antenna needs about the same height as an inverted V but is only 1,5m wide. The first results I had with this antenna were very encouraging.
8. Batteries - LiFePo and LiPo
LiFePo and LiPo batteries |
The batteries I use portable are LiFePo's and LiPo's. They offer a lot of capacity for a low weight. I use S3 LiPo's for the FT-817 and S4 LiFePo's for the FT-857. The S4 LiFePo's maintain a higher voltage than the S3 LiPo's. The FT-857 would shutdown on the LiPo's quite quickly. The FT-817 keeps on running up till the moment when the batteries reach 9,7V - so the S3 LiPo's are a good match (and they weigh less).

9. Masts - Fiberglass and aluminium
Spiderbeam HD - 12 meter and 17m fiberglass pole |
The Spiderbeam HD pole is thicker, more sturdy but also heavier than most fiberglass poles in the market. I own a 12m, 17m and 26m version. I bought the 17m version for my inverted V's on 40m and 80m. Especially the 80m version is too low on the 12m pole.
As aluminium poles I use:
- a light retractable pole normally used by window cleaners. It can be extended to approx 9m. It will hold the ventenna dipole when guyed on 1 level.
- a homebrew retractable mast consisting of 7 aluminium tubes of approx 2m that fit with a margin of 2mm. I push the tubes up by hand and lock them in position using clamps. The tubes are of a large diameter allowing me to use the mast with the 4 element yagi or the hexbeam without guying.
