Spieth HF Portable Antennas

Content of this page

DK9SQ Funktechnik bought by WiMo (April 2008)

The inventor of the well renowned Fibreglas Telescope Towers, Walter Spieth (DK9SQ) has decided to close his business DK9SQ Funktechnik after more than 30 years of active duty. His well known products (masts, SQ Vertcal, SQ Loop) will still be availabkle - we will continue to produce these fine antennas.

Note: For construction of these antennas please use only the original Spieth Fibreglas Telescope Tower, do not use our low cost versions. The low cost masts do not have the reinforcement rings at the telescope elements, but these are required for proper installation.

SQ Loop




SQ Loop

A portable quad loop for 10 to 40m, also to be installed on a Fibreglas Telescope Tower (not included). Setup in 5 minutes. The loop diameter is approx. 8m. Ideal for vacation or fieldday situations, works as a loop on 10 to 30m, folded dipole on 40m, bi-square on 10m, or as wideband vertical on 10 to 80m (even 160m). Band switching is done with connectors integrated into the antenna wire. Includes balun with PL connector for coax feed. Max. power load is approx. 300 W SSB PEP or CW. Requires a matchbox for operation (not included).

Glas fibre mast



Bild Fiberglasmast 10m

Length is 10m. Don't compare with the cheap fishing rods! Significantly better and more stable version specially developed for antenna applications. Very firm by using 3-tier lamination, virtually resistant against ultra violet light by means of blackened coloring.
Excellent vertical stability by means of individually cut friction areas. An 8-9 meter high mast supports one 2m HB9CV or a lightweight short wave dipole. Extend or collapse within a few seconds.
This is an ideally suited quick-mast for use on a balcony, in the garden, in vacation or for the field day and in case your landlord doesn't like fixed antenna installations. The set-up time of a wire vertical is typically 1 minute or 5 minutes for a light weight dipole, break-down time 30 seconds!
No foundation is required. Affix on the balcony with a rope or by using tape to fix on the car mirror or attach to a wooden support during field day - that's it! Very easy transport and fits in every car trunk. No problem for air transport carry-on.
Total length 10m, retracted 1.15m. Weight 1.5 kg. Base diameter ca.50 mm, in 9m height ca.10mm.

The mast is no longer available.
