I have been using a remote rig setup with separate RX/TX mountain sites for many years now, but every winter I get severe problems with heavy ice loads on my antennas and my 5 GHZ radio bridges and with that “sky-high” SWR and wireless dropouts.
In december 2019 I decided to build a 1/4 wave Inverted L-antenna for 160 meter, and a 80-meter long beverage on ground antenna at my Ranch.
The vertical leg of the 1/4 wave inverted L-antenna for 160 meter is 20 meter high, and the bend is facing west. The feedpoint is 90cm above ground, where I have mounted a Balun Design 1:1 Choke balun type 1116ds with 20 raised radials at 1 meter above ground. All radials are 1/4 wave in lenght.
I use a 170 meter long RFA 1/2″ low loss coax from my radio shack to the antenna, and with 100W from my ICOM IC-7100 I have about 90 watts into the antenna feedpoint.
Living down in a deep and narrow valley surrounded by high mountains, I am pleasantly surprised by the very good coverage of this 1/4 wave inverted L-antenna for 160 meter, and this is some of the dx stations I have had contact with on 160 meter band in CW the last few weeks :
NP2J, XE2X, V31MA, WG3J, K7SV, K2UO, VE3CRG, K2OS, K9IT, W1AO, K3JO, AA1K, AK1MD, K4NA, K2RR, N1RR, W8RA, K5GN, W3KL, N1DZ, KG2KJ, N9NC, N0FW, K4WMS, W3NRJ, N1PGA, JA1BXS, VE3PN, WK3A, N3XZ, W8MJ, KM4HI, W0FLS, W2GDJ, NV3N, K6LZ, NY2PO, KV0Q, VA5DX, N4AF, K1ZZ, KL0R
And all this wonderful DX contacts, running only 90 watts into the antenna feedpoint!
As receiving antenna I use a 80-meter long beverage on ground in East – West direction, with the wire about 40cm above ground.
I use a DX Engineering RTR-2 Modular Receive-Transmit Interface with the RPA-2-PM Receive Preamplifier and Receiver Guard 5000HD Plug-in Module. This way I get the opportunity to use the receiving antenna, with my ICOM IC-7100 transceiver.
This is how K2RR was heard on my beverage on ground antenna this morning. I got 579 from Rich, running only 90 watts into the antenna feedpoint.
The soil at Eikesaas Ranch has a very high level of Iron and Copper, and I am quite sure that this is the reason for the very good receiving and low power transmitting coverage I’m experiencing.
I also belive in spending hundreds of hours, optimizing both the receiving and transmitting antennas.
