ARLA/CLUSTER: Interessante debate na África do Sul entre antenas em polarização horizontal versus antenas em polarização vertical para contactos a longa distancia em VHF

[João Costa > CT1FBF]

Horizontal versus Vertical antenna polarisation - the debate

Attend the next joint *SARL* and *AMSAT SA *VHF workshop on Saturday 25 May
and join the debate about Horizontal versus Vertical antenna polarisation
for long distance VHF communication.

The subject has for several years been surrounded by arguments that
Vertical polarisation surpasses Horizontal polarisation in achieving long
distance communication on VHF with equal opposite arguments.

*Dick Coates, ZS6BUN* has carried out extensive technical paper research
and reviewed experiential data from world-wide resources and will present
his findings and share his own experiences at the workshop.

Other discussions at the workshop include: Update on the Bethlehem and
Karoo two metre beacon projects, the West Coast propagation phenomena and
three quick fire 10-minute sessions covering the Reverse beacon project,
increasing levels of the HF noise floor a growing concern and why VHF and
UHF have an important future in Amateur Radio.

The workshop will be held at the SARL National Amateur Radio Centre from
08:30 and ends at 13:00. Midmorning light refreshments will be served.

The registration fee is R50 for SARL and AMSAT SA Members and R100 for
non-members. To register, get details on www.sarl.org.za or
