TABULA TIONS OF PROPAGA TION DA TA OVER IRREGULAR TERRAIN IN THE 230- TO 9200-MHz FREQUENCY RANGE

Part III: North Table Mountain - Golden

p. L. McQuate, J. M. !"farman, M. E. McClanahan, and A. p. Barsis

This is the third part of a four -part report containing tabulations and graphs of transmission loss data resulting from propagation experiments in the 230 - to 9200 -MHz frequency range conducted over irregular terrain in Colorado. This part describes data obtained at a common receiver site, which is located on a high mesa near Golden, Colorado, over propagation paths varying in length from 0.5 to 80 km.

Key Words: Elevated antennas, irregular terrain, UHF propagation data

1. Introduction

The purpose of this four -part report series is to present

tabulations of transmission loss data for propagation over irregular

terrain in Colorado with path lengths ranging from 0.5 to 120 km at

seven frequencies in the 230 - to 9200 -MHz range.

The measurement program. was sponsored by the U. S. Army

Electronics Command and the U. S. Security Agency as a part of a

study of propagation characteristics under conditions resembling the

operations of an army in the field.

Part I of this series (McQuate, Harman, and Barsis, 1968)

presented data obtained at a common receiver site R1 located near

the summit of a hill in the open plains area near Boulder. Colorado.

Several of the transmitting sites were located in the mountains west of

Boulder; all others were located in the relatively open and rolling

plains area.

Part II of this series (McQuate, Harrnan, Johnson, and Barsis,

1968) presented data obtained at a common receiver site R2, located

in the mountains about 20 km west of Boulder. The mountains shield this

site from the plains. Only 8 of the 44 transmitting sites associated with

this receiving location are in the plains area.

This, the third part of the four-part report series, presents data

obtained from common receiver site R3 located on the eastern edge of

a high mesa (see fig. 1) at a juncture between the mountains and the

plains. The mesa, identified as North Table Mountain, is located

Figure 1. View of the common receiver site from

a point near the transmitter site R3-5-T1.

about 3 km northeast of Golden, Colorado, and is visible to most of

the 57 transmitting sites associated with the common receiver site.

This site was selected to represent propagation from the ground to

. low-flying aircraft. To obtain as many different propagation paths

as possible, all measurements were made with mobile transmitters

and a fixed receiving site.

2. Measurement Program

Figure 2 presents an overall view of the measurement area

and the distribution of the transmitter locations. It shows most of

the 57 measurement locations arranged in concentric circles around

the common receiving site at nominal distances of 0.5, 3, 5, la, 20,

3D, 40, 50, 55, 60, and 80 km.

Figures 3 and 4 are panorarnic views of the measureme nt area

taken from the antenna tower at the common receiver site. The bearings

are measured clockwise from true north. All transmitting sites lie east

of the mountains in the relatively open and rolling plains area. No

transmitting sites are located in the city of Denver or near the Stapleton

International Airport approach corridor east of the city. Most of the

transmitting sites were selected to provide a clear, unobstructed

foreground in the direction of the receiving antenna. However, eight

transmitting sites were selected so that the transmitting installation,

including the antennas, would be at least partly concealed from the

receiving antenna at the transmitting terminal by the surrounding

vegetation to represent a "concealed" location. Each concealed site

has a II companion" open site; i. e., a site with a clear unobstructed

foreground in the direction of the receiver. These sites are selected

so that they are not more than 100 m apart and have essentially a

common terrain profile.

All transmissions were continuous wave and frequencies of 230.

410. 751. 910. 1846, and 9190 MHz were used with horizontal polari

zation only.

3. Receiving Equipment

The seven frequencies were divided into two groups and separate

receiver trailers and transmitter vans were outfitted for each group.

Figure 5 shows the low frequency group (230. 410, and 751 MHz) receiver

trailer at common receiver site R2 and figure 6 shows the receiver

trailer, at common receiver site Rl, used for the four higher frequencies

(910, 1846, 4595, and 9190 MHz). Both figures show the antennas

associated with each frequency group mounted on rnovable carriages

attached to identical towers. The carriage can be installed on any of

the four tower faces and can be raised or lowered between the limits

of land 15 krn above ground at a speed of approximately 0.6 m/sec.

A servo system, attached to the antenna carriage, drives a strip-chart

recorder upon which continuous signal strength versus antenna height

recordings were made.

Figure 7, a photograph taken from a ledge on the eastern face of

the mesa, shows the receiver antenna tower at the R3 location with the

910-, 1846-, 4595-, and 9190-MHz receiving antennas elevated about

11 m above the ground and the great difference in elevation between

this common receiver location and the valley below it. The photograph

also indicates that the tower is not erected on the edge of the mesa.

It is set back about 8 m from the edge to provide s pace for guying.

This set- back causes the edge of the mesa to obstruct most of the paths

at low receiver antenna elevations (at elevations up to 2.0 m above

ground for the 3- km paths).

The same type of transmitting and receiving antennas were used

for each frequency, and the electrical characteristics of each pair of

antennas were al.so almost identical. These parameters are given in

table 1. The voltage standing-wave ratio of the antenna systems, as

viewed from the receiver inputs, exhibited essentially no change as the

antennas were moved up and down the tower.

Propagation data for the higher four frequencies were obtained

between June 21 and August 5, 1966, and data for the three lower

frequencies were obtained between September 9 and October la, 1966.

4. Transmitting Equipment

The transmitting equipITlent was housed in two ITlobile vans;

one was used for the three lower frequencies, the other for the four

higher frequencies. Figures 8 and 9 show the vans at separate trans

mitting sites. The antennas were ITlounted side by side on a framework

attached to a rigid mast that pivoted in elevation and azimuth on a base

mounted on the top of the transmitter van. This arrangement assured

constant antenna height for each frequency group (6.6 m for the lower

frequency group and 7. 3 m for the higher). After the antenna assembly

had been raised and before transITlission, the antennas were oriented to

the path azimuth by a siting device ITlounted on the antenna mast, if the

common receiver location was visible, or with the aid of a compass when

the receiver location was obscured by terrain or atmospheric conditions.

5. Data Presentation and Tabulations

The data are arranged and coded as in parts I and II of this

report series; i. e., by path distance and for each distance sequentially

by azimuth counted clockwise froITl true north. For exaITlple, R3-10 -T4

indicates a 10-km path from the common receiver site R3 to transmitter

T4, which is the fourth site at the 10-kITl distance counted clockwise

from true north. Pairs of open and concealed sites are denoted by the

standard site designation followed by "open" or "0" for open or

unobstructed sites, or "concealedl ! or II e" for sites that are at least

partly concealed by vegetation at the transmitter site.

The data for each transmission path usually comprise three

pages arranged in the following order:

The first page includes site designation and code with the

photograph(s) of terrain taken at the transmitter site in the direction of

the receiver.

The second page contains a graph of basic transmis sion los s

ver sus receiving antenna height derived from the path-los s measurements

with the site designation and code and measurement data for each group

indicated; only data from open sites are shown here. In addition to the

free-space basic transmission loss, values of maximum measurable

loss are also indicated for all frequencies, if the received signal level

was below the receiver noise level.

A number of these graphs do not show curves for all seven

frequencies. Curves for some frequencies are omitted because of

equipment malfunction, temporary inaccessibility of transmitter sites,

obvious calibration errors, and misalignments of antennas.

The third page shows aga~n the site code and includes the following:

(a) The path profile, with site elevation and path length

indicated, drawn in each case by using an effective earth radius

based on a surface refractivity value of 290 N -units. This

represents an average for the area where the measurements

were made.

(b) The results of the time recording before each height-gain

run, shown below the path profiles and designated II L b( dB) short

term signal variability". The 50 percent value is defined as the

dB value exceeded 50 percent of the time during the time recording

period and the 10 - 90 percent value is defined as the dB difference

15

between the levels of the received signal exceeded for 90 percent

and 10 percent of the time recording period.

(c) Field notes describing the terrain and significant obstacles

along the transmission path.

Additional pages (where applicable) include data for the "0" and

II C" pairs of basic transmis sion los s ver sus receiving antenna height,

and pertinent profile information, time run data, and descriptive

material related to the concea'led site.

9. Meteorological Information

This section of the report presents a comprehensive listing of

meteorological parameters for eac-h path that was obtained simultan

eously with the path loss measurements. Wet and dry bulb temperatures

were obtained by reading electrically operated psychrometers; atmos

pheric pressures were indicated on high-grade aneroid barometers;

percent relative humidity was calculated from meteorological data

obtained at the site. Cloud types were based upon the U.S. Weather

Bureau cloud code classification, and percent cloud cover, wind speed,

and wind direction were estimated.
