The left antenna (A) has:
1. Smaller in height.
2. More number of small radius turns
3. Small base (magnetic mount)
The right antenna (B) has:
1. More height
2. Less number of turns which larger radius comapared to A.
3. Large base (magnetic mount)
4. Extra Single turn above multiple turns.
Q1: How can i determine the dB gain of antenna?
Q2: If there is no relevant measuring instrument available, can i choose the best among two just on mere physical dimensions?
Q3: What is the purpose of helix/spring in both the antenna?
Q4: What is use of extra helix in Antenna-B?
