| TYPE | BRIEF DESCRIPTION | |
| AWF | A permanent fixed transmitting whip aerial fitted in many surface units. It operates in the HF band with a maximum efficiency in the region of 7MHz and with medium powered transmitters - up to 1kW. The aerial rod consists of four tapered steel rods screwed together to form a length of 35 ft. With light weight rods it becomes AWF[M]. It is mounted on a base tuner, the ETA. The aerials are usually sited in the after part of the ship or well away from the receiving whip aerials. Connected directly to associated transmitter in non-ICS ships and through the EY Exchange on ICS ships. | |
| AWN | This is an entirely lightweight monopole whip aerial outfit designed
primarily for use with common aerial working [CAW] for receivers. Four
tubes, when assembled together, form a 30 ft whip aerial of 2¼
inches outside diameter at base and tapering to 1 inch diameter at top.
It is mounted on a Group 'OA' deck insulator and fitted forward in the
ship [including on top of the main gun] and away from the ship's
transmitter aerials.

| AERIAL FEEDERS AND MATCHING [RECEIVERS] GROUPS OA, OB, OC. | The correct matching of a receiver to a feeder line and aerial need
not be so accurate as with a transmitter. Coaxial cable is
therefore used as the feeder line instead of a trunk outfit. The
aerial is secured to a deck insulator [DI], the coaxial cable being led
from the insulator to the receiver either direct of via a aerial
exchange outfit. When the coaxial cable is very long a DI
containing a matching transformer [Group OA] is fitted to avoid
unacceptable mismatch. Similarly some aerial exchange boards are fitted
with matching transformers to allow for aerials normally fitted for
Bridge Wireless Office [BWO] reception [ie., for short feed lines] to be
used, via the aerial exchange, for a receiver in the Lower Receiving
Room [LRR]. For receivers in the LRR a Group OA DI is fitted. Two
transformers A and B are fitted inside the cover plate and connected to
the aerial by means of two 3-position links. Position A = 15 to 1500 kHz
= transformer A; Position B = 100 to 10,000 kHz = transformer B;
Position C = for above 10,000 kHz = no transformer. The DI's
are filled with grease and fitted with a grease nipple. Group OB DI's
allow for straight through connections and have no transformers.
Normally fitted in large ships for BWO receivers. Group OC DI's is a
smaller version of Group OB and fitted in FF's and below. When a
matching transformer is used connection is made using low impedance and
when not used, connection is by high impedance to the receivers.

| WIRE AERIALS | Wire aerials for each ship class were made and repaired as per
Admiralty Surface Weapons Establishment [ASWE] Specification B.608.
Original fits were supplied by Builders and Dockyards, but thereafter,
wire aerials were maintained by ships staff. Because of the
exhaust fumes, gases, smoke etc from the ships funnel's and the effects
of sea spray, wires aerials had a finite life. Main roofs were
changed in their entirety at least once in an eighteen month
commission, and main roofs were regularly lowered to deck level piece
meal in order that the glass insulators could be washed and returned
aloft in good order. Vertical single wire receiving aerials, always
sited forward in the ship suffered less from corrosion than did
horizontal transmit wires and their associated vertical elements of
ships superstructure broadband wires.

| EARLY RIGS |
Here are two good examples of early aerial rigs at a time when clearly
there was no shortage of wire, and certainly there was an abundance of
rigging skills in our dockyards. Both are circa 1913. One is the
Euryalus and the other the Kongô. Euryalus is in the form of a jpeg and
its story [and this picture] features in the 1913 story of Naval W/T on
this site. Kongô is published as a PDF because I want you to zoom in on
all that beautiful 'knitting' or aerials aloft. In my time I have
taken part in main roof aerial rig changes in big ships like the Depot
Ship Tyne and to a lesser degree in a Type 12 frigate [Rothesay] , a
cruiser [Tiger] and of course, a submarine jumping wire which runs
forward to aft over the top of the periscope stanchion's, but this has
no competitors! Kongô carried
more wire aloft than any other ship in all history of W/T fits. Click here to read about the Kongô
For the record, Nelson's Column is 185 ft high with Nelson himself adding a further 17 foot, an overall height of 202 ft. Can you just imagine that ship ? This is an article about the Kongô 
Click here for the PDF and the jpeg. Go to a high zoom factor to see the aerials properly.

| HMS Royal Oak |
Our first casualty of WW2, which was sunk at Scapa Flow by a German
U-Boat in 1939. She had two TR's, No 1 with a Type 36C TX and No 2 with
a Type 49C TX, and these drawings from the Signal School in
Portsmouth date from December 1935. In the third picture showing her
rigged with experimental wire aerials in 1937 note the two TR's and
their respective positions on that same deck with the upper one {No 1 on
the port side} and the lower one on the starboard side. Apart from No 1
and No 2 main aerials, note the auxiliary aerial trunk and
the enormous size of the Port Trunk at a whopping 18 inches.

| HMS Iron Duke |
The Iron Duke was the same generation of ships as the Royal Oak above,
only two years older having been completed in 1912. This file shows
Fig's 1-3 of her experimental wire aerial rig in 1937, drawing produced
by the Portsmouth Signal School.

It once belonged to HMS Glorious when, as built, she was still a Cruiser. In the 1920's, completing in 1930, she was converted into a Carrier. Very early in WW2 [1940] she was sunk by the German ships Scharnhorst and Gneisenau in the Norwegian Sea. 
These are pictures of her as a Carrier and as a Cruiser
