| Here are the parts for the
main bracket that connect the antenna to the mast. The big bracket on
the right can be anything that provides support. |
These tubes are 3.25 inches long. 3/4,
5/8 and 1/2 inches OD. The smaller tubes slide into the larger tubes.

 |
| The 1/2 x 20 2.5 inch long
SS bolt connects the SO239 connector bracket to the mast assembly.

Completed mast assembly with SO239
connector installed. This picture shows how all the components come
together. |
 |
 |
| This is 14 inches of center
conductor from RG8. Note the tip of the RG8 is on the outside of
the SO239. This is critical to tuning the antenna. |
The antenna is made of 3/8 inch rolled
tubing or racing fuel line. You will need two pieces 53.75 inches long.
Richard forms these loops on a wood spool jig. Notice the shorting
blocks used on the gamma match. Note drawing for spacing. |
 |
 |
| These are the shorting
blocks for the gamma match. They are 2.25 inches long and the holes are
drilled .50 inches centered from each end. The white block is a RK Radio
secret but our sources have discovered that Richard gets these from the
used up paper cash registers rolls used at Burger King restaurants.
|
Chassis mount SO239 works well and takes
up less space. |
 |
 |
| All the tubing
together makes for a nice fit! Richard likes to cover everything
with Monarch RTV 100 or DAP Aquarium 100% Silicone. |
The opposite side. Not the
PVC bracket and brace below the main bracket. |
 |
|
| A piece of tubing and
tie-wraps hold the tuned section of the loop together. |
|
 |
 |
| This is a picture of
Richards stacked 6, 2 and 70 cm loops. Yep, the 70 cm is really up there
and very small. |
Another angle. |
 |
 |
| Richard checks everyone of
his antenna's to make sure they are right. The SWR on these antennas are
fairly flat across the board on the SSB frequencies! |
Richards seals everything with this
stuff. |

Meet Richard Kitchen the designer
and builder of this fine antenna. If you don't feel like
building one of these antenna's drop by Richard's shop and buy a
fully assembled version. You will be glad you did! |
