[Antennas] RF exposure regulations

Tue, 19 Mar 2002 10:39:47 -0800

A European ham of my acquaintance recently mentioned to me that he felt
constrained to put up an inconspicuous HF vertical at his home, for fear
that if he installed anything larger, hundreds of protesters would swarm
around his residence.

Apparently these demonstrators go after cell-sites, broadcast transmitters
and anything else which "radiates". Funny thing is, they use cellphones to
organise their protests. Go figure.

It is possible that the FCC promulgated the amateur RF-exposure regs under
political pressure. The Commission may have felt the need to throw a sop to
forces which might otherwise have gone after much bigger game, such as
broadcasters, wireless providers and even military comms and radar sites.

Up here in the Northlands, we are spared all of this, along with CC&R's,
10/12m-blocked HF linears and cellular-blocked UHF receivers.

I've also heard that the original 'scientific' research was judged
flawed by a peer committee [several years after the study was released].
The original investigator was barred from grant funds for a short period
of time [my recollection is that it was for 3 years]. I recall that the
original investigator was from a university in the NW USA.

However, by the time this became known the regulations had been written,
promulgated and issued.

I retired from engineering 2 years ago and can't recall the source or
journal where this was posted. If anyone has more info it would be
useful to post it.

The regulations are the regulations. Until such time as they are revoked
we have to comply. If someone chooses to challenge them they are free to
do so.
