The effective height of this heat barrage was two miles, or less.

"Scan indicated probable effective height of twenty kilometers."

A moat was a common addition to medieval fortifications, and the principal purpose was to simply increase the effective height of the walls.

In telecommunication, the effective height of an antenna is the height of the antenna's center of radiation above the ground.

In principle, such a radiator should be as thin as possible, although thicker radiators improve the bandwidth and contribute to a taller effective height.

The new station will transmit at just only 1.2 watts (non-directional antenna with an effective height of antenna above average terrain of -2.6 metres.

As he slid his foot forward, he decreased his effective height by maybe an inch, which automatically increased the upward slope of his arms by a proportionate degree.

In low-frequency applications involving loaded or nonloaded vertical antennas, the effective height is the moment of the current distribution in the vertical section, divided by the input current.

When he stood, he leaned forward, reducing his effective height to tall-human; when he walked, it was not on heels and soles but on his toes, in an alien rhythm.

Modulus and corresponding deck heights are manufactured in steps (modulus in steps of 25 mm, and effective heights in steps of 50 mm)

If thick flooring (e.g. thick hardwood planks) are added on top of the subfloor, it will cover part of the first riser, reducing the effective height of the first step.

If a race is started on some form of ramp, having a tail-heavy car can also improve final acceleration, as the effective height of the centre of gravity of the vehicle is raised.

With an ideal "infinite capacitance" top load wire, the current in the vertical would be constant along its length, giving an effective height equal to the physical height, therefore increasing the power radiated fourfold.

This formula shows that the radiated power depends on the product of the base current and the effective height, and is used to determine how many 'metre-amps' are required for a given amount of radiated power.

Why, not a-" Lady Orele was shorter and far more slender than the Lord Hulgor, but her present position in midair placed her feet at a most effective height for dealing with accosting lords.

The power radiated (or received) by an electrically short vertical antenna like the T is proportional to the square of the "effective height" of the antenna, so the antenna should be made as high as possible.

Without the horizontal wire, the RF current distribution in the vertical wire would decrease linearly to zero at the top (see drawing a above), giving an effective height of half the physical height of the antenna.

The new station would broadcast on the frequency 94.7 MHz (channel 234LP) with an effective radiated power of 50 watts (non-directional antenna with an effective height of antenna above average terrain of 8.3 metres).

Height above average terrain (HAAT) (or less popularly, EHAAT, Effective Height Above Average Terrain) is a measure of how high an antenna site is above the surrounding landscape.

On August 17, 2011, Rawlco Radio received CRTC approval to change the technical parameters of the station by increasing the effective height of antenna above average terrain from 148.4 to 272 meters and by relocating its transmitter.

The licensee also proposed to change the authorized contours by relocating its transmitter and increasing the effective radiated power (ERP) from 44.8 to 50,000 watts (non-directional antenna with an effective height of antenna above average terrain of 118 metres).

Artificial entrenchments can provide defilade by allowing troops to seek shelter behind a raised berm that increases the effective height of the ground, within an excavation that allows the troops to shelter below the surface of the ground or a combination of the two.

On February 27, 2012, the station received approval from the CRTC to increase CIIG-FM's effective radiated power from 25 watts to 32 watts (directional antenna), and decreasing the effective height of the antenna above average terrain from 55 to 30 metres.

On April 23, 2012, McBride received permission to change the technical parameters of the station by relocating the transmitter site, increasing the average effective radiated power from 470 to 540 watts, and by increasing the effective height of the antenna above average terrain from -193.2 metres to -155.1 metres.

However, the remedy will most likely consist of attaching either a metal or masonry chimney cap over the top of the opening (a chimney cap increases the effective height of the chimney and channels air flow across the opening), or a few more courses of bricks to extend the chimney to a greater height.
