1. [TowerTalk] Where is all the energy gone? (score: 1)

Ron, KU7Y compares DX77 and homemede 24' GP with 40 radials 40' long. He claims 3S units DX77 advantage on 20/40m and the opposite at 30m of FT-1000MP. Both antennas are fed with CATV 75 Ohm coax. Ro

Hi Ron, I am writing an article about trap losses for our local club magazine and in the process I have to explain that the antenna gain is the product of directivity and efficiency. You 3 antennas h

3. [TowerTalk] RE: 6db per s-unit? (score: 1)

Ron, KU7Y provides accurate reference for S9 at HF, ie. 50uV. VHF uses 5uV only as they live in quieter world and can't generate as much power as we do on HF but admitedly, they have better and light

4. [TowerTalk] Trap resonance (score: 1)

W4RNL gives advice on traped dipole for 160 and 80m and sugests tuning trap for resonance on 3,4 MHz, well bellow 80m band? I'll assume that 3,75 MHz figure would be much better for wide USA 80m band

5. [TowerTalk] S-meters linearity (score: 1)
Author: S56A@S55TCP.ampr.org (Marijan Miletic)
Date: Mon, 11 Aug 97 15:25:44 EDT
Modern HF RX with wideband input and high first IF has no particular problems with S-meter linearity as witnessed by few recent serious reviews in QST, CQ DL and Radcomm magazines. There are some ham

6. [TowerTalk] Traped antenna for 2:1 freq range (score: 1)
Author: S56A@S55TCP.ampr.org (Marijan Miletic)
Date: Mon, 11 Aug 97 22:15:23 EDT
LB, W4RNL was giving advice on traped dipole for 160m and 80m and sugests using trap on 3.4 MHz in order to equalize the gain. It sounds to me as M$ science. One can hardly expect shortened 160m dipo
