Antennas

Antenna W3DZZ of sky colour

It is perfect antenna for bands 80 and 40m, it also works satisfactory in bands: 20, 15 and 10m.
It is made of very firm and solid materials. In band 40m, a centric part of antenna works, sections are cut away by parallel resonance circumference, called traps.
Built on the base of long term experience, made of different materials, starting with energetic cords wires of different profiles with and without isolation and bands that are typically military antenna, made of phosphoric-bronze material.

The conclusion was:

SOONER OR LATER ANTENNA HAS BURST OUT!!!

My construction is antenna made of firm and solid materials, performed in solid and careful way.

I used stainless screws and I protected them using varnish; toroid balun 1:1 has been made in tight casing which is centric shackle at the same time. Shackles are made of porcelain and material which is resistant for atmosphere conditions. A cord used for radial part is a 3mm steely-brass cord in PCV (almost like copper resistance),nautical, plait silky-polypropylene cord which is to tie an antenna. Very strong section of a cord is used to fix concentric wire which prevents a plug from breaking away.

An antenna is very mobile and thanks to applied nipples, it is very easy and fast to install.

• Reliability:
  - antenna cord, long term working loading - 70 kg (and 300 while breaking away)
  - nautical cord used to tie 4mm antenna; 170 while breaking away
  
• Antenna contains:
  - toroid balun 1:1
  - antenna cord covered with isolators and thimbles (lenghts:10,07m + trap + 6,7m), total electric length - approximately 34m, it is advantage because Dipol is 40 on the 80 m band
  - nautical cord to tie antenna 10 m
  
• Antenna weight: 2,0 kg

Antenna does not contain concentric wire, toroid balun is finished with UC1 socket. For special request, I can supplement RG58 or RF-7 wire.

Additional information:
I will made Dipol antenna for different bands, Delta, toroid balun.
