- Some photos of an HD-100 Tower being installed in Southern Maine.
Radio Station - KA1HDV, Eliot, Maine
job brought on our first tower shipment into the great state of Maine. Allan, the
owner of this HD-100, is a dedicated and well known 160 meter operator and
installed this tower for the sole purpose of using it as a shunt-fed vertical transmit
at 1.8 Mhz, primarily for DX operations from this hilltop QTH. An extensive
system is a key player in this HD-100's performance on Topband.
tower site is located on a very pronounced hilltop, so assembly space was limited.
A good shot here showing the custom radial plate atop the concrete pad.
remaining 90' of tower shown here fully assembled on the ground.
Fixed-Mount Mast Plates are shown here in Section# 10 which will support a
extension mast above the top of this tower to help lower the resonate frequency.
lift point here is about 30' from the top of the tower (near Section 7/8 joint).

also showing the upper 20' of mast used for resonance.
step bolts have not yet been installed, so the climber is climbing down the towerbracing.
the skies finally begin to clear, we have an excellent shot taken here of the HD-100.

you hear a loud 160 meter signal coming from Southern Maine, it will likely be Allans.
