Magnetic Balun End Fed Zepp Wire Antenna

Installed on 8th February, 2008

The Magnetic Balun End Fed Zepp Wire Antenna:

Background:

Most built-in antenna tuners have a limited range for impedance matching. They often

only match impedances between 10-200 ohms. A End Feed Zepp Wire Antenna (LW)

with it's high impedance is not possible to match. Since a longwire antenna in most cases

is located at a distance from the station/tuner, you cannot connect a low-impedance

coaxial cable at the antenna feedpoint.

The Solution:

Is to use a broadband transformer, which transforms the impedance down to 10 times

and brings down the high impedance to a value close to 50 ohms and which the tuner

can match. Because of low SWR, the losses are now kept to a minimum.

In this case:

I ordered a Magenetic Balun fron UK - The DX System Radio MLB balun is rated for

300 Watts. As I wanted to be able to operate on 7MHz, I therefore cut the wire length to

33 feet and 1.5 inches in length and installed it on 8th February, 2008. The coaxial cable

will never experience a SWR of more than 3:1 . The wire used was 2.5mm diameter,

the coaxial cable used was the 50 Ohm grey coloured 5D2V from Kansai Tsushin Densen.

A magnetic transformer should not be used with an antenna, which is alomst resonant at the operating frequency and thus very close to 50 ohm impedance . In that case the impedance will be transformed down to 50/10 = 5 ohm which may be difficult for the tuner to handle.

The beauty of this MLB balun is that it could be connected up to any large metallic object such as a fence, the body of a car, a large roll of wire. The best and most efficeint way is to connect it up to a length of wire (as long as possible), but should at least be a 1/4 wavelength of the lowest frequency to be operated on

The antenna is useable on 7, 10, 14, 18, 21, 24, 28 and 50MHz.

40 Meter Vertical Antenna Construction

This is stage one of my 40M Veritical Project - Conversion from a 27MHz 5/8

lambda vertical antenna started on 15/02/2008.

Stage 1:

1. Removal of the 27MHz coil from inside the antenna base;

2. Removal of the SO-239 socket from the base as it is not used;

3. Drilling holes and attachement of small nylon cutting board to base - this will

be used to glue the 100 mm diameter 7MHz loading coil (on the underside of

the board). The coil is made from a 100 mm uPVC section of pipe with 6

turns of insulated 6 mm single strand copper wire for Hi-Q. The coil is now

being wound.

4. Length of the antenna is 5.35 meters. This resonates at 14.1750 MHz exactly

so without a coil you could have a mono band vertical for 20 meters.

See the photos of stage one below:

Photo 1 above: The loading coil and the SO-239 socket from the base of the

27 MHz vertical has been removed as it will not be used. The nylon board has

been fixed to the base of the vertical. The 100 mm uPVC loading coil for 7 Mhz

that is 6 turns of insulated 6 mm single stand copper wire (for Higher Q) with then

be glued to the bottom of the nylon board coil platform with expoxy resin glue.

Photo 2 above: side section showing the mounted nylon coil platform and the

RF connection point from coil to radiator element. The 100 mm diameter 6

turn 7MHz coil will be mounted underneath the nylon coil platform.

Stage 2 is the making and winding of the 7MHz loading coil.

THE COIL

This is used to make the antenna resonate at lower frequencies. I wound my coil using 6 mm

insulated copper wire, the oruginal version by SM0VPO called for 4 mm wire. I choose 6 mm

for a higher "Q" factor which should make some difference on a low band such as 7 MHZ.

The coil is 100 mm Dia (the same as a tin of Del Monte pineapple chunks)! The coil pitch is 1cm

per turn. I used a length of white uPVC pipe as the coil former to support the coil. Copper tube

can easily be soldered also.

FEEDING THE ANTENNA

Feed the antenna with 50 ohm coaxial cable, braid connected to the bracket and the center

conductor conneted via solder lug to the coil. Coils can be wound for the following bands:-

0 turns = 14 MHz (20 meter band) (VSWR - almost 1:1)

2 turns = 10 MHz (30 meter band) (VSWR - almost 1:1)

6 turns = 7 MHz (40 meter band) (VSWR - about 1.1:1)

51 turns = 3.8 MHz (80 meter band) (VSWR - about 1.4:1)

52 turns = 3.75 MHz (80 meter band) (VSWR - about 1.4:1)

53 turns = 3.7 MHz (80 meter band) (VSWR - about 1.4:1)

54 turns = 3.65 MHz (80 meter band) (VSWR - about 1.4:1)

55 turns = 3.6 MHz (80 meter band) (VSWR - about 1.4:1)

56 turns = 3.55 MHz (80 meter band) (VSWR - about 1.4:1)

57 turns = 3.5 MHz (80 meter band) (VSWR - about 1.4:1)

In my case I decided to solder a solder lug to the center pin of an SO-239 Socket

which would then be attched to the stainless steel nut and bolt terminal at the bottom

of the loading coil and again fixed solid with some aradite expoxy glue. The electrical

connections will all then be sealed in silicone for weatherproofing.

Stage 2: The 7 MHz Loading Coil

The completion of winding of the HQ loading coil was made on 16/02/2008.

The photos below show the completion of the loading coil for the 40 Meter

Vertical Antenna.

The coil is wound on a 100 mm uPVC pipe that is used as the coil former.

Stainless steel nuts and bolts used for the coil connection points and 6mm insulated

copper wire is used to wind the 6 turns for the coil.

The coil was first set in place using "Sellery" nylon cable clips setting the coil pitch

spacing at 1 cm, these are stuck into place using AA glue. Once this is done the coil

is then smothered in expoxy glue to ensure no movement and that it is robust.

The shiny surface you see is the dried epoxy glue, although it is not asthetic,

it serves the purpose of strengthening the coil.

Photo above: Somewhat ugly (encased in epoxy), the 7 MHz HQ loading coil. The coil

connection points on left are staineless nuts and bolts.

Photo above: Close up of the "Sellery" nylon cable clips used to hold down the coil and

determine the 1 cm coil pitch.

Stage 3: Attaching the loading coil to the coil platform. Saturday 23/02/2008

Today I went to Reclamation Street to buy a piece of 150mm x 190mm Bakelite to

finish the modular coil platform. I also purchased some nylon nuts and bolts for the

fastening of the coil platform to the underside of the antenna.

The bakelite sheet was HK$10.00 and cut to order, nylon nuts and bolts were HK$1.50

each.

The two photos show the coil now glued to the bakelite and fastened to the nylon

platorm. A weatherproof case is also attached which has the SO-239 connector

affixed. This is almost now finished except for the wiring connections to the antenna

itself.

Photo above: Vertical view of the 7MHz coil glued to the baklite sheet and the afixed to the

nylon coil platform using nylon nuts and bolts. The SO-239 Connector box is also attached.

Photo Above: Side view of the 7MHz Coil Platform Assembly completed on 23/02/2009. Now for the wiring

work.

Stage 4 ~ 8th and 9th March, 2008 - Final Stages.

On Saturday I mounted the antenna pole on the roof along with the ground connecor.

A 5 foot heavy duty aluminium pole is used for the mast, tis was mounted to an existing

railing using 4 nos. of 4" staineless steel hose clamps.

I also reinforced the main vertical bracket section of the vertical by attaching a uPVC

bottom section in order to give additional strength to this section as the original diameter

of aluminium tubing used was thought to be a little under engineered. The photos below

show the strengthening of the bottom section of the aluminim braket section. The uPVC

tube is fixed rigidly to the aluminium tube by use of epoxy glue and silicone sealant.

Sunday 9th March I will concentrate on the final electrical connections of the coil to the

vertical element and if time and weather permits, the final assembly of the vertical,

measuring and erection of the antenna onto the mounting pole.

Photo Above: Shows the uPVC tube glued to the top element section using epoxy and silcone glue to

ensure no movement. The purpose id to strenghen the lower portion of the vertical antenna.

Photo Above: showing the top section of the uPVC reinforcement section just before the connection points

for the upper tubing sections.

Photo Above: Shows the bottom Vertical Antenna mounting bracket in relation to the reiforced section.

The photos below show the 7MHz Antenna Mounting Pole and grounding put into place

and ready to receive the antenna.

Below are two photos showing the antenna first mounted on it's pole late afternoon on

9/3/2008, the Hi-Q base loading coil and platform can be clearly seen underneath.

Finally, the whole antenna was erected, connected up and coaxial cable connected at 5:45pm

on 9/3/2008 and I was able to test out the SWR. A flat 1.5:1 SWR across the SSB portion of

7MHz, not to bad for a homebrew antenna effort. With a little tuning on the antenna tuner it is

1:1 on the SWR meter. Now I need some propagation to test it. The photos below show the

antenna completed at twilight, it stand over 17.5 feet in the air.

POST INSTALLATION NOTE: 11/3/2008 ~ Further Adjustment of the connection leads and

the ground return wire yielded an SWR reading of 1.15:1 !!! I can't expect more.

RX Antenna Distribution - 6 Way Splitter System

A simple project underway to make a splitter distribution board for one Antenna input

and 6 RX outputs to various receivers using:-

1 x Super Star Splitter Model 1022 [2 way splitter, 5-1000MHz, F Female Connectors];

2 x Super Star Splitter Model 1023 [3 way splitter, 5-1000MHz, F Female Connectors].

These will be fixed to a bakelite board and interconnected with 50 ohm coaxial cable

and then the input and outputs will be terminated in 50 ohm SO-239 sockets. The

splitters all have grounding terminals and are made of die cast housings, all of which

will be terminated to common ground.
