WHAT’S NEW ? AL HISLOP Electrical Engineer CARE July 1, 2003

TWO MAJOR CHANGES SINCE 1999 DENIAL DIRECTIONAL ANTENNA PATTERNS DIRECTIONAL ANTENNA PATTERNS LOWER TOWER LOWER TOWER

LCG RF REPORT SAYS RF INCREASES TO SOUTH AND EAST RF EMISSIONS STUDY CONCLUSIONS, LCG Ex. 17, CARE Ex. 80, Pink Divider

RF LEVEL INCREASES RF LEVEL INCREASES WHY? RF ERP INCREASED BY 9 MEGAWATTS RF ERP INCREASED BY 9 MEGAWATTS ANTENNA PATTERN MAXIMUM TO SOUTH ANTENNA PATTERN MAXIMUM TO SOUTH See LCG Ex. 17 ANTENNAS NOT ABOVE POPULATED AREA ANTENNAS NOT ABOVE POPULATED AREA

LCG Lookout Mt. ERP Increase LCG ERP on Lookout Proposal = 9,732,000 watts Proposal = 9,732,000 watts Present = 732,000 watts Present = 732,000 watts

JEFFERSON COUNTY TOWER SITING REQUIREMENTS TOWER LOW WITH RESPECT TO RIDGELINE ANTENNAS LOCATED ABOVE POPULATED AREAS THE LCG SITE CANNOT COMPLY

NEGATIVES OF LOW TOWER DESIGN LOW TOWER = INCREASED RADIATION IN COMMUNITY LOW TOWER = INCREASED RADIATION IN COMMUNITY Antennas mounted length of tower Antennas mounted length of tower

ANTENNAS POINT DIRECTLY AT RESIDENCES MY HOME LIKE ENRON AND WORLDCOM

RF LEVELS EXPRESSED AS µW/cm 2 USE OF % MPE IGNORES INTERFERENCE POTENTIAL USE OF % MPE IGNORES INTERFERENCE POTENTIAL USE OF % MPE CAN MASK RF INCREASES USE OF % MPE CAN MASK RF INCREASES

ONLY 15.2 μW 8.4µW 6.5µW 4.0µW 3.3µW

DISCONNECT FROM TRUTH LCG SAYS RF LEVELS WILL GO DOWN LCG SAYS RF LEVELS WILL GO DOWN JEFFCO’S CONSULTANT MR. HART CONFIRMS RF LEVELS WILL INCREASE OVER WIDE AREA LCG CLAIMS QUIET ZONE EXEMPTION LCG CLAIMS QUIET ZONE EXEMPTION NO DTV QUIET ZONE EXEMPTION EXISTS

QUIET ZONE ISSUE CAN AFFECT LOCAL RF LEVELS BY LAW, LCG CANNOT USE PROPOSED BY LAW, LCG CANNOT USE PROPOSEDANTENNAPATTERNS LCG MAY ROTATE PATTERNS 90 DEGREES LCG MAY ROTATE PATTERNS 90 DEGREES LOCAL LEVELS TO WEST WOULD INCREASE LOCAL LEVELS TO WEST WOULD INCREASE

SOLUTION TO QUIET ZONE PROBLEM: ROTATE PATTERN LOW FIELD TO NORTH HIGH FIELD TO WEST LOW FIELD TO WEST

ANTENNA PATTERNS NOT IN ODP IF APPROVED, JEFFCO HAS NO CONTROL OF ANTENNA PATTERNS IF APPROVED, JEFFCO HAS NO CONTROL OF ANTENNA PATTERNS NO GUARANTEE OF REDUCED RF TO WEST NO GUARANTEE OF REDUCED RF TO WEST RF INCREASES MAY BE EVEN HIGHER THAN CALCULATED IN POPULATED AREAS RF INCREASES MAY BE EVEN HIGHER THAN CALCULATED IN POPULATED AREAS LCG HAS HAD YEARS TO RESOLVE LCG HAS HAD YEARS TO RESOLVE

COSMIC BACKGROUND RADIATION “ BREAKTHROUGH IN UNDERSTANDING THE ORIGINS OF THE UNIVERSE” FEB 2003 NASA RELEASE MAP SPACECRAFT

INTERFERENCE EXAMPLE: MOUNTSFIELD AVE. ALREADY EXPERIENCING HIGH INTERFERENCE PROBLEMS ALREADY EXPERIENCING HIGH INTERFERENCE PROBLEMS RF POWER DENSITY FROM LCG MEMBERS ALONE WOULD DOUBLE FROM 7.5 TO 15.2 μW/cm 2 RF POWER DENSITY FROM LCG MEMBERS ALONE WOULD DOUBLE FROM 7.5 TO 15.2 μW/cm 2

MOUNTSFIELD LCG LEVEL COMPARED TO BLANKETING INTERFERENCE LEVEL 180 x BLANKETING MOUNTSFIELD

INTERFERENCE TLUP : ANTENNAS ABOVE RESIDENTIAL AREAS TO MINIMIZE INTERFERENCE. TLUP : ANTENNAS ABOVE RESIDENTIAL AREAS TO MINIMIZE INTERFERENCE. LCG INTERFERENCE REMEDIATION PLAN LCG INTERFERENCE REMEDIATION PLAN ONLY A FEW DEVICES ONLY A FEW DEVICES ONLY ONE YEAR. ONLY ONE YEAR.

LCG INTERFERENCE PLAN LIMITED IN SCOPE AND TIME INTERFERENCE NOT COVERED INTERFERENCE COVERED

FCC Ignores 4 CARE Petitions for Relief from Interference March 9, 1999 Ex. 35 October 17, 2000 Ex. 36 August 23, 2002Ex. 89 September 20, 2002 Ex. 89 Result-No help from FCC

LOCATE TOWER AWAY FROM PEOPLE PROPER LOCATION AWAY FROM PEOPLE AND BUSINESSES WOULD MINIMIZE INTERFERENCE WOULD MINIMIZE INTERFERENCE FOR ALL DEVICES FOR ALL DEVICES ALL THE TIME ALL THE TIME Why a one year plan for a 50 or 100 year project?

NO SUBSTITUTE FOR PROPER SITING HIGH POWER BROADCAST FACILITIES AWAY FROM POPULATED AREAS. HIGH POWER BROADCAST FACILITIES AWAY FROM POPULATED AREAS. DOES NOT CONFORM WITH RESIDENTIAL INTERFERENCE POLICIES. DOES NOT CONFORM WITH RESIDENTIAL INTERFERENCE POLICIES.

ALTERNATE SITES EXIST SQUAW MOUNTAIN RECEPTION TESTS: SQUAW MOUNTAIN RECEPTION TESTS: EXCELLENT RESULTS SQUAW MOUNTAIN ALREADY ZONED FOR TV BROADCAST SQUAW MOUNTAIN ALREADY ZONED FOR TV BROADCAST

LCG’S CONCERNS ABOUT SQUAW MOUNTAIN “LOST VIEWERS” “LOST VIEWERS” INADEQUATE SPACE INADEQUATE SPACE “VERTICAL REAL ESTATE”

WHAT THE FCC SAYS YOU NEED IF YOU DON’T HAVE THIS MUCH SIGNAL, LCG SAYS YOU ARE A “ LOST VIEWER ” HOW MUCH SIGNAL DO YOU NEED?

SPACE REQUIREMENTS SQUAW MOUNTAIN ZONED FOR THREE 200 FOOT TOWERS SQUAW MOUNTAIN ZONED FOR THREE 200 FOOT TOWERS AT MOST 3 ANTENNAS NEEDED TO ACCOMMODATE LCG DIGITAL AT MOST 3 ANTENNAS NEEDED TO ACCOMMODATE LCG DIGITAL ANALOG REMAINS UNTIL PHASEOUT ANALOG REMAINS UNTIL PHASEOUT

REAL REASON LCG CHOSE LOOKOUT MOUNTAIN REAL REASON LCG CHOSE LOOKOUT MOUNTAIN LCG LETTER TO JEFFCO PLANNING: March 6, 1998 “Fourth, and perhaps most importantly, Lake Cedar Group controls a large assemblage of property on Lookout Mountain.”

CONCLUSION THE LCG PROPOSAL THE LCG PROPOSAL INCREASES RF LEVELS OVER A LARGE POPULATED AREA INCREASES RF LEVELS OVER A LARGE POPULATED AREA DOES NOT MEET INTERFERENCE POLICY DOES NOT MEET INTERFERENCE POLICY STAFF AND JEFFCO RF CONSULTANT, STAFF AND JEFFCO RF CONSULTANT, MR.
