EFHW- Dipole with Traps

While searching for an alternative to my Linked- Dipole I tripped over the posting of Pedro, CT1DBS, illustrating an end-fed half-wave (EFHW)- Dipole with Traps. Here is the Link to his article. With this design changing bands can be done in no time thaks to the traps. Lowering or modifying the antenna is no longer necessary.

DM/BW-094 – Kornberg – 779m

Abstract

April 20, 2017  12:05 – 13:05 UTC
Partly cloudy, approx. 6°C
Walking time 30 min. up, 20 min. down

Rig: KX3 / 10W, 2200mAh LiPo, Palm Pico Paddle
Ant: End Fed Half Wave Dipole with Traps (40m – 30m – 20m) on a tree (apex: 7m)

6 CW QSOs on 20m, 4 CW QSOs on 30m, 26 CW QSOs on 40m.

Kornberg can be reached from Gruibingen. The car park (Aeussere Kornbergsteige) is hard to miss. There is a signpost (Bushaltestelle) „Kornbergsattel“ on the way to Gammelshausen.
Like many summits of the „Schwaebische Alb“, Kornberg is wooded but the top is free of trees. This makes it a very nice place to stay. However, there is no panoramic view from the top.

Luckily most of the clouds disappeared while climbing Kornberg and the temperature became more pleasant. I set up the station next to a tree and my antenna as inverted Vee.
This is a very nice and remote summit and I’ll most likely return next year.

DM/BW-664 – Wasserberg – 751m

Abstract

April 20, 2017  09:50 – 10:15 UTC
Overcast, approx. 0°C
Walking time 20 min. up, 10 min. down

Rig: KX3 / 5W, 2200mAh LiPo, Palm Pico Paddle
Ant: End Fed Half Wave Dipole with Traps (40m – 30m – 20m) on a tree (8m)

1 CW QSO on 20m, 7 CW QSOs on 30m, 8 CW QSOs on 40m.

Wasserberg is yet another wooded summit. It can be reached from the car park (Wanderparkplatz Gairenbuckel) close to „Gairenhof“ near Schlat.  Finding the actual summit is easy with GPS assistance.

On April 18th we had lots of snow and it stayed for a couple of days. So this was rather a winter activation. When reaching the summit I noticed that I left the insulating cushion in the car. Hence activation was very uncomfortable sitting on my gloves.
Activity on 20m was low and resulted in just one QSO. After QSY-ing to 30m the activation qualified. It was freezing cold and I was quite happy to QRT after 25 minutes.

DM/BW-156 – Lindenberg – 949m

Abstract

April 14, 2017  14:10 – 15:15 UTC
Overcast, approx. 12°C
Walking time: Zero – Lindenberg is a drive- on location

Rig: KX3 / 10W, 2200mAh LiPo, Palm Pico Paddle
Ant: End Fed Half Wave Dipole with Traps (40m – 30m – 20m) on a GRP Pole (6m)

7 CW QSOs on 30m, 55 CW QSOs on 40m

Lindenberg can be reached directly by car from Ippingen, when choosing the road to the north.

It was a good final for the day but again unspectacular. Didn’t bother to get to the actual summit but set up my station when reaching the activation zone. The spot was without panoramic view so I only took a single picture during setup.

Conditions on 20m were poor again. But 40m was in excellent shape and kept me busy for almost 45 minutes.

Set up the station on a couple of trunks close to the track.

DM/BW-057 – Lupfen – 977m

Abstract

April 14, 2017  12:30 – 13:00 UTC
Partly cloudy, approx. 11°C
Walking time 10 min. up, 10 min. down

Rig: KX3 / 5W, 2200mAh LiPo, Palm Pico Paddle
Ant: End Fed Half Wave Dipole with Traps (40m – 30m – 20m) sloping from the tower down to the trees.

4 CW QSOs on 20m, 4 CW QSOs on 30m, 22 CW QSOs on 40m

Lupfen can be reached from the car park (Wanderparkplatz) north of Talheim. The trail leads straight to the east, up the hill.
When I reached the summit, the last visitors had left the tower. So I decided to set up my shack at the top, the antenna sloping down into the trees. Conditions seemed to have further improved, thus the number of QSOs was even higher than on Hummelskopf.

After the activation I took a short break in the sunshine before I headed to the last destination of the day, Lindenberg (DM/BW-156).

DM/BW-845 – Hummelskopf – 867m

Abstract

April 14, 2017  10:15 – 10:55 UTC
Overcast, approx. 9°C
Walking time 35 min. up, 25 min. down

Rig: KX3 / 10W, 2200mAh LiPo, Palm Pico Paddle
Ant: End Fed Half Wave Dipole with Traps (40m – 30m – 20m) on a GRP Pole (6m)

9 CW QSOs on 30m, 17 CW QSOs on 40m

Yet another wooded plateau. I could have got nearer to the top by choosing a different car park but opted for an easy- to- find trail. Nevertheless, GPS was helpful to locate the actual „summit“.

The top of Hummelsberg was completely unspectacular, no panoramic view, just a little clearing. No surprise that I forgot to take a picture from the actual summit.

Condx had improved in the meantime and subsequently more QSOs went into the log.

DM/BW-195 – Zundelberg – 954m

Abstract

April 14, 2017  07:55 – 08:20 UTC
Overcast, approx. 7°C
Walking time 25 min. up, 15 min. down

Rig: KX3 / 10W, 2200mAh LiPo, Palm Pico Paddle
Ant: End Fed Half Wave Dipole with Traps (40m – 30m – 20m) on a GRP Pole (6m)

13 CW QSOs on 40m.

First activation in 2017.

Zundelberg can be reached from Hausen o.V. The car park (Wanderparkplatz Gehrnhalde, 882m a.s.l.) is a bit out of town. Like many summits of the „Schwaebische Alb“, Zundelberg is completely wooded. Finding the actual summit without GPS can be tricky.

I set up the station at the foot of the wooden tower. Conditions on 20m and 30m were poor and the RBN didn’t spot me on these bands! Only after QSY-ing to 40m I was able to log a dozen QSOs.

SOTA Equipment – updated

This is what my equipment looks like after I started a programme to reduce the weight (s. the 2 kg Challenge). I’m going to use it on long hikes and trips to high summits where weight comes into play.

sota-light

From left to right: EFHW- Dipole with traps (40m, 30m, 20 m), 10m Nylon rope (red), tent peg, antenna bag, Unun 1:64, 1m RG58, bag for MTR 3B and Palm Pico Paddle, earplugs,  1250mAh LiPo battery 2S, power cable with fuse, 3 velcro straps, lashing belt, tape, writing board with log sheets, pencil, spare fuse, headlight, 3 x 10m guy rope with tent pegs, support plate 8mm (for guy wires), army knife,  6m fiberglass telescopic pole (57cm long).

The equipment as shown in the picture weighs 2067 grams. However, it is possible to leave the guy ropes out and attach the GRF pole to the summit cross using the lashing belt. Additionally, if a 1000mAh LiPo will be used instead of the 1250mAh LiPo, the total weight of my equipment is slightly above 1700 grams. This is 3 kg less than what I’m usually carrying around and definitely a big improvement.
