TET- Emtron HF antennas

Proudly made in Australia!
 



TEV-1 broadband HF vertical allows 3.5~30MHz operation

$279 AUD

In stock!

The TET-Emtron model TEV-1 is an 8.5 metre long vertical broadband HF antenna. It comprises six 1.5m long sections of aluminium tubing.
All stainless steel hardware and rugged aluminium construction ensure long and reliable operation.

The TEV-1 should be mounted on top of a metal pole. The antenna's height may be set from 30cm (one foot) above ground level to virtually any height above ground. 

In the case of mounting the TEV-1 above a metal roof, it should be mounted at a height of at least 2m in order to reduce excessive ground reflection. The antenna is predrilled.

By following the simple instructions, you will find that the antenna is quite easy to assemble.

TEV-1's impedance range is typically in the range of 200~300 ohms.
Fitting a 4:1 balun to the TEV-1's feed point will reduce that impedance range to 50~75 ohms, making it easy for almost all coaxial cable feed antenna tuners to match that impedance range to 50 ohms.
Fitting a 4:1 balun establishes an intermediary impedance transformation between the 50 ohm impedance of the coaxial cable feed  and the 200~300 ohms feed point of the TEV-1.

We have found that coax cable feed automatic antenna tuners fitted internally in many modern HF SSB amateur radio transceivers will often tune the apparent SWR down to <1.5:1 when transmitting into a TEV-1 with a 4:1 balun fitted at the TEV-1's feedpoint. These automatic antenna tuners typically have an
impedance tuning range of 16~150 ohms (i.e. up to 3:1 SWR).

The same situation applies to similar design external automatic antenna tuners made by the same amateur radio transceiver manufacturers.

Whether internal, or external, these conventional design automatic antenna tuners typically employ air-spaced tuning capacitors which limits their impedance matching range to about 3:1.

By comparison, automatic antenna tuners which have microprocessor controlled selection of a wide range of fixed/lumped inductors and capacitors often have impedance matching ranges around 10:1...    

Some methods of feeding the antenna are:

  • By fitting a 4:1 balun at the feed point, then running 50 ohm coax to a tuner in the shack
  • Directly with a long wire into a high impedance tuning auto tuner (e.g. most LDG tuners or an Icom AH-4 or MAT tuner), then into 50 ohm coax cable which would go into the shack
  • Inductively, by fitting a series base loading coil
  • Directly with 450 Ohm ribbon, then into a 4:1 balun and antenna tuner at the shack
